Xbase64 is useful for accessing data in legacy dBase 3 and 4 database files as well as a general light-weight database engine. It includes support for DBF (dBase version 3 and 4) data files, NDX and NTX indexes, and DBT (dBase version 3 and 4). It supports file and record locking under *nix and Windows. DIRECTORY LAYOUT ---------------- /bin contains various utility programs /examples contains various test programs /html contains the original xBase documentation in html format /xbase64 Xbase64 source and header files BUILDING THE LIBRARY ON UNIX/LINUX ---------------------------------- XBase64 uses autoconf and libtool to manage the build process. To configure the library for your specific system, run the "configure" shell script as follows: ./configure The configure script accepts the following options in addition to the normal default options: --enable-debug creates debugging code [default=no] --enable-shared build shared libraries [default=yes] --enable-static build static libraries [default=no] --with-gnu-ld assume the C compiler uses GNU ld [default=no] --without-index-ndx turn off .ndx index support --without-index-ntx turn off .ntx index support --without-memo-fields turn off memo fields support --without-expressions turn off expressions support --without-xbase-locking turn off XBase file locking --without-realdelete turn off XBase record deletion --without-xbase-debug turn off XBase specific debug --without-largefile-support turn off XBase largefile support Once configured, execute make as follows to build the library: make Once compiled (and assuming no errors occurred), use make to install the library, header files, and utilities as follows: make install The default install directory is /usr/local. BUILDING THE LIBRARY ON WINDOWS ------------------------------- The MINGW32 and CYGWIN compiler support didn't make the first cut to Xbase64. They will be migrated forward in a future release of xbase64. Any volunteers? If using the MINGW32 GCC compiler package, use the makefile.g95 make files. Edit bin/makefile.g95 xbase/makefile.g95 to change installation directories. If using the CYGWIN environment, use the makefile.cyg make files (or fix the autoconf/automake stuff to work correclty). However, for some reason (as yet undetermined) it seems to run very slowly when compiled with the cygwin compiler (perhaps the file handing in the cygwin dll is just dog slow?). BUILDING THE LIRARY WITH BORLAND 5.5 ------------------------------------ There are batch files MAKEBCC.BAT which build the xbase libs for Borland C++ 5.5. DOCUMENTATION ------------- The documentation at this point consists of the original xBase documentation (in the html directory). It is still very useful as little has changed from the original library except bugfixes and a few enhancements. We are working on incorporating comments into the source to allow generation of reference documentation using the Doxygen document generator. A small amount has been done already, but we hope to complete this effort before the next release.

The remainder of this file is the generic installation instructions included with automake/autoconf. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/kde/bin', `/usr/local/kde/lib', etc. You can specify an installation prefix other than `/usr/local/kde' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. xbase64-3.1.2/docs/0040755000000000000000000000000010057170456012430 5ustar rootrootxbase64-3.1.2/docs/Makefile.in0100755000000000000000000001350110057165472014477 0ustar rootroot# Makefile.in generated by automake 1.6.3 from Makefile.am. # @configure_input@ # Copyright 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ SHELL = @SHELL@ srcdir = @srcdir@ top_srcdir = @top_srcdir@ VPATH = @srcdir@ prefix = @prefix@ exec_prefix = @exec_prefix@ bindir = @bindir@ sbindir = @sbindir@ libexecdir = @libexecdir@ datadir = @datadir@ sysconfdir = @sysconfdir@ sharedstatedir = @sharedstatedir@ localstatedir = @localstatedir@ libdir = @libdir@ infodir = @infodir@ mandir = @mandir@ includedir = @includedir@ oldincludedir = /usr/include pkgdatadir = $(datadir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ top_builddir = ..

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! ----------------------------------------------------------------------------- GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

There are significant changes in this release. 1) The original author (Gary Kunkel) has resumed working on the project. 2) The project was branched and renamed to xbase64 with 64 bit file processing capabilities. The xbase name is being used by other projects, so I thought it was time for a new name. 3) Modified the license from LGPL to GPL as recommended by the GNU web site. Files that I have not been able to get permission from the original author for GPL terms have beed deleted from the library. 4) Trimmed the tree: Dropped support for the xbHtml class, the turbo vision interface, and the ybase directory. These are either unused, not working, undocumented, not maintained, or I didn't have authority to change the license from LGPL to GPL. 5) Didn't move make files forward that were not documented or working. These need to be reviewed and brought forward. 6) Worked on the locking logic. 7) Added support for Borland C++ 5.x compiler. 8) Created a new data type of XB_BOOL. Current bool data type was causing issues in certain environments. 9) Dropped support for XB_CASTELLANO dates. Changed the logic to use system locale settings, this supports descriptive dates in different languages. 10) Cleaned up memory leaks. 11) Updates to the documentation. 12) Enhancements to the expression logic 13) Fixed the broken index logic - the ndx and ntx indices are working again. ----------------------------------------------------------------------- For a the historical NEWS file history (pre 9/15/03), review the older xbase library. xbase64-3.1.2/html/0040755000000000000000000000000010057170456012444 5ustar rootrootxbase64-3.1.2/html/xbase.jpg0100755000000000000000000001442507526567160014267 0ustar rootrootÿØÿàJFIFÿÛC    $.'

The LGPL below is copyrighted by the Free Software Foundation, but the instance of code that it refers to (the XBase libraries) are copyrighted by the authors who actually wrote it. --------------------------------------------------------------------------- GNU LIBRARY GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1991 Free Software Foundation, Inc. 59 Temple Place - Suite 330 Boston, MA 02111-1307, USA. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the library GPL. It is numbered 2 because it goes with version 2 of the ordinary GPL.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Library General Public License, applies to some specially designated Free Software Foundation software, and to any other libraries whose authors decide to use it. You can use it for your libraries, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library, or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link a program with the library, you must provide complete object files to the recipients so that they can relink them with the library, after making changes to the library and recompiling it. And you must show them these terms so they know their rights. Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the library. Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license. The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined work, a derivative of the original library, and the ordinary General Public License treats it as such. Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing, because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better. However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will lead to faster development of free libraries. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, while the latter only works together with the library. Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one. GNU LIBRARY GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Library General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also compile or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. c) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. d) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Library General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15.

    Expression Handling

    Chapter Updated 3/12/04

    Overview

    The main objective of this chapter is to provide information regarding the basic concepts of using the Xbase Expression module.

    Beginning with release 1.7.4, the Xbase library includes an expression parsing routine which assists application programmers by providing a high level data manipulation tool and also allows for building complex index keys. The functions included were derived from dBASE III Plus, but not all dBASE III Plus functions have been implemented yet.

    Release 3.0 brought some upgrades to the expression module of the library including bug fixes, additional operators and new functions. The expression module is usable and functional, but has some room for improvement. A future release of Xbase will include more comprehensive expresion logic.

    Internal fuctioning

    The expression module works in two phases. Firstly, method ParseExpression is called and builds an expression tree from all the components of the expression. The tree is made up of indivdual nodes. The expression is checked for valid field names, literals, operands and functions. Any field references are resolved. If fields are used in an expression and the database name for the field is not included in the name with the -> operand, the routines assume the associated database has been successfully opened.

    Secondly, method ProcessExpression is called to process the expression tree created by ParseExpression(). The routine parses each node in the expression tree, executing functions, processing operands and manipulating data to produce the desired result.

    If an expression will be processed repeatedely, it is best to pre-parse the tree using ParseExpression, then for each new call to the expression, execute method ProcessExpression which processes the tree.

    Expression Return Types

    Expressions will return a type of CHAR *, NUMERIC or LOGICAL.

    An expression return type can be determined with method GetExpressionResultType after parsing it.

    Expressions returning a return type of CHAR are limited to a 200 byte internal buffer. There is also a 100 byte limit for NDX index key support. If the 200 byte limit is not large enough for your application, adjust field enum { WorkBufMaxLen = 200 }; in file exp.h.

    Expression Functions

    Each expression function also has a corresponding C++ function. It is slightly more efficient to call the C++ functions directly, rather than execute the expression parsing routines.

    Expression Components

    Expressions are made up of one or more tokens. A token is one of literal, database field, operand or function. Literals are either numeric or character. Character literals are enclosed in 'single' or "double" quotes. numeric literals are a series of one or more contiguous numerals, ".", "+" or "-'".

    A field is simply a field name in the default database, or is in the form of database->fieldname.

    Sample Program Demonstrating Expression Processing

    Record and File Locking

    Chapter Updated 2/1/99

    Locking Overview

    Xbase DBMS supports multi-user processing through file and record locks. Record locking restricts multiple cooperating programs from simultaneously accessing the same data and corrupting it. Without record and file locking in a multi-user environment, simultaneous access to the data and index files can cause the files to become inaccurate and unusable.

    Record locking is on by default in the Xbase DBMS library. To disable it, comment out the XB_LOCKING_ON option in the options.h file in the xbase/src directory.

    The current Xbase DBMS record locking does not co-exist with other Xbase products and there is not yet support for locking in a DOS/Windows environment. The locking functions do work correctly for a Xbase DBMS only configuration. Future version of Xbase DBMS will have enhanced locking features for co-existing with other Xbase products and also include DOS/Windows support.

    The locking methods return either XB_LOCK_FAILED or XB_NO_ERROR. If they return XB_LOCK_FAILED the actual reason can be found in the global variable errno or function perror() can be executed to view the results.

    The errno field may contain one of the following values if the lock was not successful.

    Error CodeDescription
    EBADFInvalid file descriptor
    EINVALInvalid lock information or file does not support locks
    EACCESS
    EAGAIN    		Lock can not be set because it is blocked by an existing lock on the file.
    ENOLCKThe system is out of lock resources, too many file locks in place.
    EDEADLKDeadlock condition
    EINTRProcess was interrupted by a signal while it was waiting


    Types of Locks

  • Write or Exclusive Locks provide exclusive access to a particular file location. No other process can lock the same location.

  • Read or Shared Locks prohibit any process from requesting a write lock on a specified part of the file. Other processes can request simultaneous read locks.


    DBF File Locking Techniques

    Xbase DBMS uses the following protocol for DBF file and record locking:

    To lock a record - the first byte of the record is locked.
    To lock the file - the header bytes of the file are locked.

    When a record is being appended to the file, the header bytes are locked.
    When a record is being updated, the header bytes and the specific record are locked.

    This locking protocol is probably not compatable with other Xbase type products. However, Xbase can be safely used for multi-user access when it is not simultaneously updating DBF or NDX files while other products/programs are.


    NDX File Locking Techniques

    Xbase DBMS locks indexes by locking the first 512 bytes of the index file. The entire index is locked because any updates to the index potentially can modify significant portions of the index tree.


    DBT File Locking Techniques

    Xbase DBMS locks memo files by locking the first 4 bytes of the memo file. This effectively locks the entire file. The entire file is locked because any updates to the free block chain can significantly change the structure of the file.


    AutoLocking Features

    If XB_LOCKING_ON is set in the options.h file, the locking methods execute any appropriate locking logic. If XB_LOCKING_ON is not set in the options.h file, all locking methods return XB_NO_ERROR without performing any actual record or file locking. This enables the application program to always call locking routines regardless of the XB_LOCKING_ON switch in the options.h file.

    By leaving the autolocking features enabled, the application program does not need to address record, file or index locking. All locking is handled automatically by the Xbase routines. However, if access to the locking routines is required, they are available to the applciation programmer.

    When the files are automatically locked by the Xbase routines, the database file is locked first, then it locks the indexes in alphabetical order. To avoid deadlock conditions, files and record locks should always be done in the same order. When the files are unlocked, then indexes are unlocked first, then the database is unlocked.

    Auto-locking works well in an on-line transaction based environment. However, it does not function efficiently in batch mode. If you will be writing programs which process files in a batch mode, disabling auto-lock and locking the entire file at the beginning of the process and unlocking the file at the end of the process will significantly reduce process time. On a 586-200 class machine, a file with 45000 records can be read thru in a few seconds with the file locked in batch mode. In record-lock mode it takes about six minutes with the same processor.

    For processing large files, locking the file instead of locking each record is far more efficient. This is how you do it.

    For reading the file in batch mode:
    xbDbf.AutoLockOff();
    xbDbf.LockDatabase( F_SETLKW, F_RDLCK, 0L );

    For updating the file in batch mode:
    xbDbf.AutoLockOff();
    xbDbf.LockDatabase( F_SETLKW, F_WRLCK, 0L );

    Xbase DBMS Record and File Locking

    Chapter Updated 4/8/98

    Locking Overview

    Xbase DBMS supports multi-user processing through file and record locks. Record locking restricts multiple cooperating programs from simultaneously accessing the same data and corrupting it. Without record and file locking in a multi-user environment, simultaneous access to the data and index files can cause the files to become inaccurate and unusable.

    Record locking is on by default in the Xbase DBMS library. To disable it, comment out the LOCKING_ON option in the options.h file in the xbase/src directory.

    The current Xbase DBMS record locking does not co-exist with other Xbase products and there is not yet support for locking in a DOS/Windows environment. The locking functions do work correctly for a Xbase DBMS only configuration. Future version of Xbase DBMS will have enhanced locking features for co-existing with other Xbase products and also include DOS/Windows support.

    The locking methods return either LOCK_FAILED or NO_ERROR. If they return LOCK_FAILED the actual reason can be found in the global variable errno or function perror() can be executed to view the results.

    The errno field may contain one of the following values if the lock was not successful.

    Error CodeDescription
    EBADFInvalid file descriptor
    EINVALInvalid lock information or file does not support locks
    EACCESS
    EAGAIN    		Lock can not be set because it is blocked by an existing lock on the file.
    ENOLCKThe system is out of lock resources, too many file locks in place.
    EDEADLKDeadlock condition
    EINTRProcess was interrupted by a signal while it was waiting


    Types of Locks

  • Write or Exclusive Locks provide exclusive access to a particular file location. No other process can lock the same location.

  • Read or Shared Locks prohibit any process from requesting a write lock on a specified part of the file. Other processes can request simultaneous read locks.

    To lock the file - the header bytes of the file are locked.

    When a record is being appended to the file, the header bytes are locked.
    When a record is being updated, the header bytes and the specific record are locked.

    This locking protocol is probably not compatable with other Xbase type products. However, Xbase can be safely used for multi-user access when it is not simultaneously updating DBF or NDX files while other products/programs are.


    NDX File Locking Techniques

    Xbase DBMS locks indexes by locking the first 512 bytes of the index file. The entire index is locked because any updates to the index potentially can modify significant portions of the index tree.


    DBT File Locking Techniques

    Xbase DBMS locks memo files by locking the first 4 bytes of the memo file. This effectively locks the entire file. The entire file is locked because any updates to the free block chain can significantly change the structure of the file.


    AutoLocking Features

    If LOCKING_ON is set in the options.h file, the locking methods execute any appropriate locking logic. If LOCKING_ON is not set in the options.h file, all locking methods return NO_ERROR without performing any actual record or file locking.

    DBF.LockDatabase( F_SETLKW, F_RDLCK, 0L );

    For updating the file in batch mode:
    DBF.AutoLockOff();
    DBF.LockDatabase( F_SETLKW, F_WRLCK, 0L );



    Method Table
    MethodDescription
    DBF::AutoLockOnTurns autolocking on
    DBF::AutoLockOffTurns autolocking off
    DBF::ExclusiveLockLock file and indexes in exclusive mode
    DBF::ExclusiveUnlockUnlock files and indexes
    DBF::LockDatabaseLocks or unlocks a DBF database
    NDX::LockIndexLocks or unlocks an NDX index
    NDX::LockMemoFileLocks or unlocks a DBT memo field file

    Method Descriptions

    Method VOID DBF::AutoLockOn( VOID )


    This method turns automatic record locking on. Auto record locking is on by default if LOCKING_ON is set in the options.h file.

    Example Program:

    See program loadzips.cpp for an example of how to use this method.

    Method VOID DBF::AutoLockOff( VOID )


    This method turns automatic record locking off. Auto record locking is on by default if LOCKING_ON is set in the options.h file.

    Turning auto locking off will result in slightly better execution speeds but should not be used in multi-user environments when multiple users can update files simultanteously. If multiple users are accessing a file which is read only then it is safe to turn off auto-locking for a particular file.

    Turning autolocking off will disable any index file locking which is particularly dangerous in a multi-user environment if updates on the files are permitted.

    Example Program:

    See program loadzips.cpp for an example of how to use this method.

    Method SHORT DBF::ExclusiveLock( SHORT WaitOption )

    Method SHORT DBF::ExclusiveUnlock( VOID )


    ExclusiveLock and ExclusiveUnclock will lock the data file, memo file (if applicable) and any associated indexes in an exclusive mode. They also turn auto-lock on and off as appropriate.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    Example Program:

    See program sample4.cpp for an example of how to use this method.

    Method SHORT DBF::LockDatabase( SHORT WaitOption, SHORT LockType, LONG LRecNo )


    This method locks or unlocks an Xbase (.DBF) file which was previously opened.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    LockType is one of:

  • F_RDLCK - Perform a Read or Shared Lock
  • F_WRLCK - Perform a Write or Exclusive Lock
  • F_UNLCK - Unlock it

    LRecNo is:

    0 - Lock the header section of the file (use this to lock the file)
    1 through n - Lock a particular record

    Method Return Codes
    Return CodeDescription
    INVALID_RECORDAn invalid record given
    LOCK_FAILEDThe lock action failed, see errno
    NO_ERRORThe lock was successful

    Example Program:

    See program loadzips.cpp for an example of how to use this method.

    Method SHORT DBF::LockIndex( SHORT WaitOption, SHORT LockType )


    This method locks or unlocks an Index (.NDX) file which was previously opened.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    LockType is one of:

  • F_RDLCK - Perform a Read or Shared Lock
  • F_WRLCK - Perform a Write or Exclusive Lock
  • F_UNLCK - Unlock it

    Method Return Codes
    Return CodeDescription
    LOCK_FAILEDThe lock action failed, see errno
    NO_ERRORThe lock was successful

    Example Program:

    See program loadzips.cpp for an example of how to use this method.

    Method SHORT DBF::LockMemoFile( SHORT WaitOption, SHORT LockType )


    This method locks or unlocks a memo (.DBT) file which was previously opened. It is not necessary for an application to call this method as locking is handled automatically by other routines.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    LockType is one of:

  • F_RDLCK - Perform a Read or Shared Lock
  • F_WRLCK - Perform a Write or Exclusive Lock
  • F_UNLCK - Unlock it

    Method Return Codes
    Return CodeDescription
    LOCK_FAILEDThe lock action failed, see errno
    NO_ERRORThe lock was successful

    Index Methods

    Chapter Updated 2/12/99

    This chapter lists the xbNdx and xbNtx index methods and provides examples of how to use them.

    There are many methods in the xbNdx and xbNtx classes which are used for maintaining and updating NDX and NTX files. Fortunately for the application programmer, most of the complexities of dealing with the NDX and NTX indices are automatically cared for by the Xbase library.

    xbNdx and xbNtx methods which are used by application programs are documented here. With some exceptions (OpenIndex,CloseIndex and KeyExists) using the index routines automatically positions and returns the associated record in the DBF database.


    Xbase xbNdx Index Method List
    MethodDescription
    CheckIndxIntegrityChecks an index file for integrity
    CloseIndexOptional, closes an index. Closing the DBF file will close any open indexes.
    CreateIndexCreate an index
    FindKeyFind a key in an index file
    GetFirstKeyGet the first key in an index
    GetLastKeyGet the last key in an index
    GetNextKeyGet the next key in an index
    GetPrevKeyGet the previous key in an index
    KeyExistsDetermine if a key exists w/o positioning DBF file
    OpenIndexOpen an index
    ReIndexRebuilds an index
    in

    Method Definitions

    Method xbShort xbNdx::CheckIndexIntegrity( xbShort option )

    Method xbShort xbNtx::CheckIndexIntegrity( xbShort option )


    This method checks an open index for accuracy or file corruption. If the option is non zero, the method will display informational messages.


    Method Return Codes
    Return CodeDescription
    XB_NO_ERRORIf there is no error
    XB_LOCK_FAILEDRead lock not successfull
    XB_NOT_OPENFile not open
    XB_INVALID_RECORDInvalid record number
    XB_SEEK_ERRORSeek routine error
    XB_WRITE_ERRORWrite routine error

    Example Program:

    See program checkndx.cpp for an example of how to use this method.

    Method xbShort xbNdx::CloseIndex( VOID )

    Method xbShort xbNtx::CloseIndex( VOID )


    This method closes an open NDX index. NDX indexes are closed automatically by the DBF::CloseDatabase routine, so this is an optional method. Closed indices are not updated by the Xbase routines.


    Method Return Codes
    Return CodeDescription
    XB_NO_ERRORIf there is no error

    Example Program:

    See program sample1.cpp for an example of how to use this method.

    Method xbShort xbNdx::CreateIndex( char * IndexName, char * KeyExpression, xbShort Unique, xbShort OverLay )

    Method xbShort xbNtx::CreateIndex( char * IndexName, char * KeyExpression, xbShort Unique, xbShort OverLay )


    This method creates an index. Indices are created as either a character based index or a numeric based index, depending on the KeyExpression value.

  • Indexname - is the name of the physical index file name.
  • KeyExpression - is the key of the index.
  • Unique - XB_UNIQUE or XB_NOT_UNIQUE
  • Overlay - XB_OVERLAY or XB_DONTOVERLAY


    Method Return Codes
    Return CodeDescription
    XB_NO_ERRORIf there is no error
    XB_NO_MEMORYMemory error
    XB_OPEN_ERRORCould not open index file
    XB_INVALID_KEY_EXPRESSIONBad index key expression
    XB_NOT_OPENThe database was not open
    XB_SEEK_ERRORSeek error encountered
    XB_READ_ERRORRead error encountered


    Index expressions can be a single field or multiple fields. Assuming a database has fields LASTNAME and FIRSTNAME, valid index expressions could be:


    Sample Index Expressions
    ExpressionDescription
    "LASTNAME"Index on LASTNAME only.
    "LASTNAME+FIRSTNAME"Index on LASTNAME and FIRSTNAME
    "LASTNAME-FIRSTNAME"Index on LASTNAME and FIRSTNAME, all spaces between the two fields removed.
    "LASTNAME-','FIRSTNAME"Index on LASTNAME and FIRSTNAME, insert a comma between the two values, remove spaces between the two fields.


    Allowable Index Expression Operators

    OperatorKey TypeDescription
    +CharacterConcatonate string fields
    -Character Concatonate string fields, remove trailing spaces
    'literal'Characterinclude literal value
    "literal"Characterinclude literal value
    +NumericAdd two numeric fields togethor
    -NumericSubtract one numeric field from another
    *NumericMulitply two numeric fields togethor
    /NumericDivide one numeric field into another
    **NumericExponential


    Example Program:

    See program sample1.cpp for an example of how to use this method.

    Method xbShort xbNdx::FindKey( char * SearchValue )

    Method xbShort xbNdx::FindKey( xbDouble SearchValue )

    Method xbShort xbNtx::FindKey( char * SearchValue )

    Method xbShort xbNtx::FindKey( xbDouble SearchValue )


    This method searches the index for key SearchValue. The routine positions in the index, then positions to the database record for the key. If the key is not found, the key value that is the next higher value is returned.

    For character keys, the SearchValue should be a null terminated string. To find an exact match, use a key value which is as long as the key is, padded on the right with spaces.

    For numeric keys, use a xbDouble value for a search value. This is because all numeric field indices are saved as double values.

    Database Overview

    Chapter Updated 3/18/04

    The objective of this chapter is to provide information regarding how the database files are utilized and document the various record structures. With the exception of the brief section on the record buffer, the information presented in this chapter is not required to use the Xbase library. It is mainly information describing internal file structures utilized by the Xbase routines.

    Xbase files are comprised of a variable length header record which stores information about the file and describes the fixed length record format, followed by a series of fixed length data records.

    Each fixed length data record is preceded by a one byte indicator which identifiies if the record has been deleted. If the record is not deleted, the indicator is a space (0x20). If deleted, the indicator contains an asterisk (0x2A). Data fields are stored in records without field separators or record terminators.

    In earlier releases of dBASE, there is an ASCII NULL character between the $0D end of header indicator and the start of the data. This NULL was removed starting with dBASE III Plus, making a Plus header one byte shorter than an identically structured III file. The methods documented in the Xbase software and documentation follow the more recent version where the NULL character is not included.

    Each database file is comprised of zero, one or many records. A record is comprised of fields. Only one record is accessed at a time.

    Zero, one or many database files can be open simultaneously.

    The Record Buffer

    When using the Xbase routines, each open data file has a record buffer which is manipulated by calling the database, index and field routines. Updates are committed from the record buffer to the database when a write, or append is performed. The library will automatically write updates to the database if the buffer has been updated and the record is repositioned or the database is closed.

    The record buffer is not used for handling the actual data portion of memo fields. When working with memo fields, the application program must allocate enough buffer space for reading and writing memo fields.

    Internal to the library, there is an additional record buffer which stores the original value of the data record before any changes are made. This is used by the index routines for finding and deleting original key values from any open indices before adding the new keys. If the key values are not changed, no index updates occur.


    Xbase Database File Header

    The Xbase file header, located at the beginning of the database, describes the .DBF database. Knowledge of this structure is not necessary to effectively utilize the Xbase libraries.


    PositionLengthDescription
    01 bytefile version number
    (03H without a .DBT file)
    (83H with a .DBT file)
    1-33 bytesdate of last update
    (YY MM DD) in binary format
    4-732 bit numbernumber of records in data file
    8-916 bit numberlength of header structure
    10-1116 bit numberlength of the record
    12-3120 bytesreserved
    32-n32 bytes eachfield descriptor record (see below)
    n+11 byte0DH as the field terminator



    Xbase Field Descriptor Record

    The Xbase field descriptor record stores information about each field in the database. Each database has from 1 to 1024 fields. Knowledge of this structure is not necessary to effectively utilize the Xbase libraries.


    PositionLengthDescription
    0-1011 bytesfield name in ASCII zero-filled
    111 bytefield type in ASCII (C N L D or M)
    12-1532 bit numberfield data address
    161 bytefield length in binary
    171 bytefield decimal count in binary
    18-3114 bytesreserved bytes (version 1.00)



    Field Data Format

    Data are stored in ASCII format in the database as follows:

    DATA TYPEDATA RECORD STORAGE
    CharacterASCII characters, left justified, right blank filled
    Date(8 digits in YYYYMMDD format, such as
    19601007 for October 7, 1960)
    Logical? Y y N n T t F f (? when not initialized)
    Memo10 digits representing a .DBT block number
    Numeric. 0 1 2 3 4 5 6 7 8 9 + -, right justified, left blank filled
    Float. 0 1 2 3 4 5 6 7 8 9 + -, right justified, left blank filled


    Memo Fields

    Memo fields store variable length data elements in a seperate .DBT file. The main .DBF file maintains a ten byte field which is used by the Xbase routines for determining the location of the data in the .DBT file.

    Xbase DBMS supports both dBASE III+ and dBASE IV version memo files. The version IV files are somewhat more efficient in that they reuse unused memo space when data are deleted or freed from use. With version III files, all new updates are appended to the end of the file and the unused space is not reclaimed until the datafiles are packed.

    Memo fields can be used for storing a variety of date type. However, type 3 files are limited to storing textual data because most internal memo field processing in a type 3 file relies on two contiguous 0x1a charaters.

    Type 4 memo fields can be used for storing BLOB (binary large object) data reliably, as the internal file structure does not rely on any special characters embedded in the data.

    A special note on storing string data in a memo field. For those users that are new to C/C++ programming, string fields typically end with a null (0x00) terminator character. As a general rule of thumb when using the library, add one to the length of any string when specifying the length of the data. This stores the null terminating byte with the data. For example, when storing string "This is a string" specified size should be 17, not 16.

    Technical memo file information

    The following info on memo fields is for the curious. It is not required reading if you don't need to know the internals.

  • Memo files are made up of one or more blocks
  • For version III files, the block size is 512
  • For version IV files, the block size is a multiple of 512
  • The minimum amout of space necessary to store one memo field is one block or 512 bytes.
  • The default block size can be adjusted by manipulating the XB_DBT_BLOCK_SIZE macro in the options.h file.
  • The main .DBF file maintains a ten byte numeric field which is blank if no memo data exists for a given field. Otherwise it contains a number, which when multiplied by the block size, points to the offset in the file of the head block in the file/

    For version 3 memo field files, there are two fields in the head block of the file, NextBlockNo and Version. Depending on the Xbase software, some vendors products update these two fields, some do not. The Xbase library keeps the fields updated, but does not rely on them to be valued with correct data. This helps to support maximum compatibility amoungst all Xbase tools available.

    For version 4 memo field files, the first block in the .DBT file is a header block which is comprised of 8 bytes of data which maintain the file's block size and the next free block available in the file. Blocks two through n contain the actual memo data. A chain of empty blocks is maintained within the file for potential future use. When an add or update routine executes, it first attempts to find a spot in a set of blocks which were earlier allocated, but not currently in use for the data. If no free spot is found, data are appended to the end of the file. The free block chain is sorted in block number order. When blocks of data are freed and added to the free block chain, the routines will attempt to concatonate free block chains togethor where possible. When a delete occurs, or an update which requires less space occurs, the new free space is added to the free block chain.

    Various Memo File Block Types

    Valid Block Types
    Head Block
    Only data block for memo field
    First of several contiguous data block set
    2-n of contiguous data block set

    xbLong4-7Number of free blocks in this contiguous free block set


    Version 3 and 4 memo fields are terminated with two contiguous 0x1A bytes of data.

    64 Bit File Support

    Beginning with Release 3.0 of the library, Xbase was renamed to Xbase64 and 64 bit file support was incorporated into the library.

    This functionality currently works on Linux/Unix platforms which support 64 bit file structures. 64 bit support was not tested with Windows because the author didn't have access to a compiler which creates 64 bit Windows apps. If you need this functionality for Windows, consider donating a Windows 64 bit compiler to the project and I'll get 64 bit support working for Windows.

    It is not advisable to use Xbase 64 bit file support in combination with 32 bit Xbase applications such as older versions of DBase, Clipper and Foxpro. Xbase64 can extend the files well beyond any limits in the older 32 bit application development environments.

    If Xbase is being built with glibc, verify it is at least version 2.2.3.

    Fields and Strings

    Chapter Updated 8/20/03



    The title of this chapter almost sounds like a popular North American magazine called Field and Stream. The difference between this chapter and that magazine is there are no dead animal carcuses or fishing lures in this chapter. For those you will need to get a copy of Field and Stream.

    The main objective of this chapter is to provide information regarding the basic concepts of manipulating data via the field methods.

    Field names can be up to ten bytes in length and can contain characters, numbers or special characters in the name. The field methods are used to manipulate the data in a record of a data file. There are several types of fields.

    Field Types
    TypeSizeAllowable ValuesSchema Value
    Numeric0 - 17(include sign and decimal point+ - . 0 through 9XB_NUMERIC_FLD
    Character0 - 254AnythingXB_CHAR_FLD
    Date8CCYYMMDDXB_DATE_FLD
    Floating Point0 - 17 (includes sign and decimal point+ - . 0 through 9XB_FLOAT_FLD
    Logical1? Y y N n T t F f (? - uninitialized)XB_LOGICAL_FLD
    MemoFixed length portion - 10
    Variable length 0 - 32760     		Type III - Text
    Type IV - Anything    		XB_MEMO_FLD


    Field names, types and lengths are defined when a data file is created. After the file is created, the field characteristics can not be changed. To change field characteristics, a new database must be defined with the new field requirements.

    Memo Fields

    Memo fields are variable length data fields which are stored in two parts. This first part is a ten byte field which is stored in the fixed length record of the .DBF file. The variable data is stored in a seperate .DBT file in 512 byte blocks. The ten byte field in the fixed length portion of the record points to a .DBT block number.

    There are two versions of memo data files type III and type IV. Type IV is more advanced in that released space can be reused and it also supports BLOB data. The type III file is older technology, does not support dynamic space reclamation and only supports string data. See method xbDbf::SetVersion for controlling which version type you are using.

    To utilize memo fields, the application program must allocate a buffer which is large enough to handle the memo data.

    Fields and Field Numbers

    The Xbase routines can access field data via using field names or field numbers. Field numbers are numbered 0-n where the first field in a datafile is field 0 going through the last field n. Accessing fields by number is more efficient than accessing by name.

    Record Schema

    The record schema of a file can be found in the documentation for method CreateDatabase in the Database Methods chapter, or view example program sample1.cpp.

    Strings

    Beginning with Release 1.8.0a, Xbase includes support for a string class xbString. The original thinking was not to include a string class in the library, and encourage users to use the string class native to the user's compiler. But as C++ does not have a native way to handle strings, and there is not a standard string class across C++ compilers, it was decided to include a lightweight string class with the library. In some cases this is redundant, but it is portable.

    The xbString class interface was derived from the Draft Standard C++ Library by P.J. Plauger and modified. If you are familiar with other string classes, this one should feel similar.

    Date Processing

    Chapter Updated 2/12/99

    The objective of this chapter is to provide information regarding the basic concepts of date arithmetic and supply generic C/C++ date methods.

    Two common things of all programmers is that if they write enough code, they will eventually have to deal with dates. They may be Julian dates, Gregorian dates, or a date with their best freind's girl, but they'll eventually be working with dates. The other thing is that most programmers don't have the time or don't want to spend time writing mundane date routines.

    To explain how dates work, I'll give a brief overview and history of Julian dates, Gregorian dates, leap years and leap centuries.

    Leap Years

    Due to the fact that it actually takes about 365 1/4 days for the earth to circle the sun, every fourth year and every fourth century have an extra day added to the end of February and the year is called a leap year. Leap years have 366 days, non leap years have 365 days. The following code segment describes how to determine if a given year is a leap year. A leap year is a year having 366 days, which can be evenly divisible by 4 and not by 100 or divisible by 400. There are also leap centuries. Leap centuries are years which are evenly divisible by 400. To calculate a leap year, the following code segment can be used int year; if(( year % 4 == 0 && year % 100 != 0 ) || year % 400 = 0 ) LEAP_YEAR = TRUE; else LEAP_YEAR = FALSE

    Julian Dates

    Around the time of Jesus Christ, a fellow with the name of Julias Ceasar established the Julian calendar. The Julian calendar established every fourth year as a leap year with 366 days and all other years having 365 days. The months were set up the same as they are with a Gregorian calendar, which is what we use today. A Julian date is defined as as the number of days from the first day of the year; February 1 would have a Julian day of 32.

    From a programmer's perspective, Julian dates are useful for doing date arithmetic, determining the difference between two dates or calculating a future or past date.

    To determine the difference between two dates, convert both dates to a Julian date and subtract one from the other.

    To calculate a future or past date, convert the base date to a Julian date, add (or subtract) the number of days necessary to (from) it and convert the julian date back to a Gregorian date.

    The Julian date routines use a base date of 01/01/1900.

    Gregorian Dates

    In 1582, Pope Gregor XIII introduced a corrected form of the Julian calendar. Every 4th year still has 366 days except for century years. Century years were added as leap years if evenly divisible by 400. The year 2000 is a leap century.

    The methods supplied with this software are based on gregorian dates with the format of CCYYMMDD for century, year, month and day.

    CASTELLANO options

    There is an option in the options.h file for enabling the date routines to return Spanish values for days, weeks and months.

    #define CASTELLANO

    Date Formats

    All dates are stored in the .DBF files with format CCYYMMDD.

    All date routines work with dates formated with the same CCYYMMDD format.

    Sample Program

    #include <iostream.h> #include <xbase/xbase.h> main() { xbXBase x; long l; cout << "\nThis program tests the XDATE routines\n\n"; cout << "\nThis year is " << x.YearOf ( x.Sysdate() ); cout << "\nThis Month is " << x.MonthOf( x.Sysdate() ); cout << "\nToday is day " << x.DayOf( WEEK, x.Sysdate()) << " of the week"; cout << "\nToday is day " << x.DayOf( MONTH, x.Sysdate()) << " of the month"; cout << "\nToday is day " << x.DayOf( YEAR, x.Sysdate()) << " of the year"; if( x.IsLeapYear( x.Sysdate())) cout << "\nThis is a leapyear"; else cout << "\nThis is not a leap year."; cout << "\nToday is " << x.Sysdate(); if( x.DateIsValid( "19951301" )) cout << "\n19951301 is a valid date"; else cout << "\n19951301 is not a valid date"; l = x.JulianDays( "19951101" ) - x.JulianDays( "19951001" ); cout << "\nThere are " << l << " days between 10/1/95 and 11/1/95."; cout << "\nIn 7 days it will be " << x.JulToDate8( x.JulianDays( x.Sysdate()) + 7L ); cout << "\nToday is " << x.CharDayOf( x.Sysdate()); cout << "\nThis month is " << x.CharMonthOf( x.Sysdate()); cout << "\nFormat (YYDDD) "; cout << x.FormatDate( "YYDDD", x.Sysdate()); cout << "\nFormat (MM/DD/YY) "; cout << x.FormatDate( "MM/DD/YY", x.Sysdate()); cout << "\nFormat (MMMM DD,YYYY) "; cout << x.FormatDate( "MMMM DD,YYYY", x.Sysdate()); cout << "\nFormat (DDDD, MMMM DD YYYY) "; cout << x.FormatDate( "DDDD, MMMM DD YYYY", x.Sysdate()); cout << "\n"; }

    Language

    Perl 5.0

    Purpose

    Convert Dbase, Clipper, FOXPRO Source Code to XBASE C++ Code for use with XBASE DBMS Library

    Output

    .cpp File and .h File

    Arguments

    1st arg = filename

    Remarks

    The script tries to keep track of the databases used in different workareas. But the flow through your program cannot be determined, so in some cases you have to help the script a bit by giving additional info.

    Three special comments have been designed to add this info:

    * XB2CPP(SelectedArea)
or  * XB2CPP(SelectedArea,Workarea1,Alias1,Wa2,Al2...)
or  * XB2CPP(SelA,WA1,Al1[Total1, Active1],Wa2, Al2[Tot2,Act2])

    e.g. * XB2CPP(3,3,ZP,2,PL) will inform the script for example at the beginning of a PROCEDURE that a database with Alias ZP is opened in workarea 3 and a database with alias PL is opened in workarea2 and when calling this procedure always workarea 3 is selected.

    The third alternative of this statement makes it possible to define the number of open indices and which one is the active index, as given by a previous SET INDEX TO or USE and SET ORDER TO statements. The script cannot know, which procedures, statements have been executed before and opened indices.... So * XB2CPP(2,2,ZP[2,1]) will inform the script about an open database alias ZP in workarea 2 which is currently selected and has two open indices where the first one is the active one.

    Hints

    1. Always give an ALIAS in USE-Statements this is needed for generation of the Database Classnames
    2. Give the above described additional infos where necessary.
    3. Use ALIASes in Expressions with database fields, this helps the script in knowing where database references are.
    4. Replace the XXX in PutXXXField or GetXXXField manually the script is not able to determine variable or field types. The code for getting a Textfield (GetField) must also be corrected. Xbase DBMS Syntax requires the buffer as second parameter, the string will not be returned ! You may use a C++ String wrapper for this job.
    5. PROCEDURES that will operate on two different databases where some statements are used for both cannot be converted The script needs to know everytime on which database the statements are operating. Either duplicate such procedures, (one for each database), or write a generic C++ routine with pointers to databases.
    6. Don't assume any compilable or even working C++ source code as output. The ambigous DBASE language, which lacks type and variable definitions is one reason for this. This script only will help you for about 10-30% of the conversion. The rest (which remained uppercase) has to be done manually :)

    Locking Methods

    Chapter Updated 2/1/99

    The locking methods return either XB_LOCK_FAILED or XB_NO_ERROR. If they return LOCK_FAILED the actual reason can be found in the global variable errno or function perror() can be executed to view the results.

    The errno field may contain one of the following values if the lock was not successful.

    Error CodeDescription
    EBADFInvalid file descriptor
    EINVALInvalid lock information or file does not support locks
    EACCESS
    EAGAIN    		Lock can not be set because it is blocked by an existing lock on the file.
    ENOLCKThe system is out of lock resources, too many file locks in place.
    EDEADLKDeadlock condition
    EINTRProcess was interrupted by a signal while it was waiting


    Types of Locks

  • Write or Exclusive Locks provide exclusive access to a particular file location. No other process can lock the same location.

  • Read or Shared Locks prohibit any process from requesting a write lock on a specified part of the file. Other processes can request simultaneous read locks.


    DBF File Locking Techniques

    Xbase DBMS uses the following protocol for DBF file and record locking:

    To lock a record - the first byte of the record is locked.
    To lock the file - the header bytes of the file are locked.

    When a record is being appended to the file, the header bytes are locked.
    When a record is being updated, the header bytes and the specific record are locked.

    This locking protocol is probably not compatable with other Xbase type products. However, Xbase can be safely used for multi-user access when it is not simultaneously updating DBF or NDX files while other products/programs are.


    NDX File Locking Techniques

    Xbase DBMS locks indexes by locking the first 512 bytes of the index file. The entire index is locked because any updates to the index potentially can modify significant portions of the index tree.


    DBT File Locking Techniques

    Xbase DBMS locks memo files by locking the first 4 bytes of the memo file. This effectively locks the entire file. The entire file is locked because any updates to the free block chain can significantly change the structure of the file.


    AutoLocking Features

    If XB_LOCKING_ON is set in the options.h file, the locking methods execute any appropriate locking logic. If XB_LOCKING_ON is not set in the options.h file, all locking methods return NO_ERROR without performing any actual record or file locking. This enables the application program to always call locking routines regardless of the XB_LOCKING_ON switch in the options.h file.

    By leaving the autolocking features enabled, the application program does not need to address record, file or index locking. All locking is handled automatically by the Xbase routines. However, if access to the locking routines is required, they are available to the applciation programmer.

    When the files are automatically locked by the Xbase routines, the database file is locked first, then it locks the indexes in alphabetical order. To avoid deadlock conditions, files and record locks should always be done in the same order. When the files are unlocked, then indexes are unlocked first, then the database is unlocked.

    Auto-locking works well in an on-line transaction based environment. However, it does not function efficiently in batch mode. If you will be writing programs which process files in a batch mode, disabling auto-lock and locking the entire file at the beginning of the process and unlocking the file at the end of the process will significantly reduce process time. On a 586-200 class machine, a file with 45000 records can be read thru in a few seconds with the file locked in batch mode. In record-lock mode it takes about six minutes with the same processor.

    For processing large files, locking the file instead of locking each record is far more efficient. This is how you do it.

    For reading the file in batch mode:
    xbDbf.AutoLockOff();
    xbDbf.LockDatabase( F_SETLKW, F_RDLCK, 0L );

    For updating the file in batch mode:
    xbDbf.AutoLockOff();
    xbDbf.LockDatabase( F_SETLKW, F_WRLCK, 0L );

    Method Descriptions

    Method VOID xbDbf::AutoLockOn( VOID )


    This method turns automatic record locking on. Auto record locking is on by default if XB_LOCKING_ON is set in the options.h file.

    Example Program:

    See program loadzips.cpp for an example of how to use this method.

    Method VOID xbDbf::AutoLockOff( VOID )


    This method turns automatic record locking off. Auto record locking is on by default if XB_LOCKING_ON is set in the options.h file.

    Turning auto locking off will result in slightly better execution speeds but should not be used in multi-user environments when multiple users can update files simultanteously. If multiple users are accessing a file which is read only then it is safe to turn off auto-locking for a particular file.

    Turning autolocking off will disable any index file locking which is particularly dangerous in a multi-user environment if updates on the files are permitted.

    Example Program:

    See program loadzips.cpp for an example of how to use this method.

    Method SHORT xbDbf::ExclusiveLock( SHORT WaitOption )

    Method SHORT xbDbf::ExclusiveUnlock( VOID )


    ExclusiveLock and ExclusiveUnclock will lock the data file, memo file (if applicable) and any associated indexes in an exclusive mode. They also turn auto-lock on and off as appropriate.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    Example Program:

    See program sample4.cpp for an example of how to use this method.

    Method SHORT xbDbf::LockDatabase( SHORT WaitOption, SHORT LockType, LONG LRecNo )


    This method locks or unlocks an Xbase (.DBF) file which was previously opened.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    LockType is one of:

  • F_RDLCK - Perform a Read or Shared Lock
  • F_WRLCK - Perform a Write or Exclusive Lock
  • F_UNLCK - Unlock it

    LRecNo is:

    0 - Lock the header section of the file (use this to lock the file)
    1 through n - Lock a particular record

    Method Return Codes
    Return CodeDescription
    XB_INVALID_RECORDAn invalid record given
    XB_LOCK_FAILEDThe lock action failed, see errno
    XB_NO_ERRORThe lock was successful

    Example Program:

    See program loadzips.cpp for an example of how to use this method.

    Method xbShort xbDbf::LockIndex( xbShort WaitOption, xbShort LockType )


    This method locks or unlocks an Index (.NDX) file which was previously opened.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    LockType is one of:

  • F_RDLCK - Perform a Read or Shared Lock
  • F_WRLCK - Perform a Write or Exclusive Lock
  • F_UNLCK - Unlock it

    Method Return Codes

    Method xbShort xbDbf::LockMemoFile( xbShort WaitOption, xbShort LockType )


    This method locks or unlocks a memo (.DBT) file which was previously opened. It is not necessary for an application to call this method as locking is handled automatically by other routines.

    WaitOption is either:

  • F_SETLK - returns immediately regardless if success or failure
  • F_SETLKW - waits until lock function executes

    LockType is one of:

  • F_RDLCK - Perform a Read or Shared Lock
  • F_WRLCK - Perform a Write or Exclusive Lock
  • F_UNLCK - Unlock it

    Xbase Return Codes

    Page Updated 2/19/04

    Beginning with release 3.0 exception processing has been removed from the library. There were reports that it was not 100% working, so I trimmed the library back to working code. If there are any volunteers to re-install the exception processing, AND test it, let me know. Thanks - Gary It is generally a good idea to check the method return codes to verify an error hasn't occured. Most Xbase DBMS methods return a SHORT return code value which corresponds to a value in this table.

    NTX Indices

    Chapter Updated 2/12/99

    The objective of this chapter is to provide information regarding the basic concepts of how .NTX index files work in the Xbase environment.

    The information in this chapter has been gathered by searching the internet and by examining the structure of known good NTX indexes.

    NTX Index File Characteristics

    • NTX indices maintain keys in ascending sort order only.

    • NTX indices support unique or non unique keys.

      Unique keys must be unique. The database update routines will fail if an attempt to add a non-unique key is performed.

      Non-unique Keys are not required to be unique, duplicate keys are allowed if the index is created with the XB_NOT_UNIQUE setting. Duplicate keys are stored in record number order.

    • NTX indexes are automatically updated by the Xbase library after the indices are opened.

    • Character keys are left justified and padded on the right with spaces.

    • Numeric keys are stored as eight byte double values.

      The numeric key processing logic performs floating point numeric calculations on eight byte double values. This logic may be compute intensive and slow on older machines, especially the older intel processors without a math coprocessor chip.

    NTX File Internals

    NTX files are comprised of two or more 1024 byte blocks or nodes of information. There are three types of nodes: Head Nodes, Interior Nodes and Leaf Nodes.

    The Head Node is the first node in the file starting at position zero (0) and contains information about the NTX file. There is only one Head Node in each index and it always starts at the beginning of the file.

    NTX Header Node
    TypeSizeField NameDescription
    xbShort2Signature ByteThe Clipper signature byte. 0x003h indicates Clipper 87. 0x006h indicates Clipper 5.x
    xbShort2Indexing Version NumberDocumented as the "Compiler Version" but I have observed an increasing number. Incremented whenever the index is changed.
    xbLong4First Node OffsetThe offset to the first node.
    xbLong4First Unused Page OffsetThe offset to the first unused node.
    xbShort2Key Size + 8The Key Size plus 8 bytes.
    xbShort2Key SizeThe size (length) of the key.
    xbShort2Number of DecimalsNumber of decimal places in key.
    xbShort2Max Items Per NodeThe maximum number of key per node.
    xbShort21/2 The Max Items Per NodeHalf the maximum number of key per node. Important in a B-tree system, as this is the minimum number of keys that must be on a page.
    char256KeyExpressionKey expression string
    char1UniqueUnique indicator
    00 - Not Unique - XB_NON_UNIQUE
    01 - Unique - XB_UNIQUE
    char745UnusedUnused
    1024Total bytes in node


    The following structure is used by the Xbase NTX routines: struct NtxHeadNode { /* ntx header on disk */ xbUShort Signature; /* Clipper 5.x or Clipper 87 */ xbUShort Version; /* Compiler Version */ /* Also turns out to be */ /* a last modified counter */ xbULong StartNode; /* Offset in file for first node */ xbULong UnusedOffset; /* First free node offset */ xbUShort KeySize; /* Size of items (KeyLen + 8) */ xbUShort KeyLen; /* Size of the Key */ xbUShort DecimalCount; /* Number of decimal positions */ xbUShort KeysPerNode; /* Max number of keys per node */ xbUShort HalfKeysPerNode; /* Min number of keys per node */ char KeyExpression[256]; /* Null terminated key expression */ unsigned Unique; /* Unique Flag */ char NotUsed[745]; };

    Interior and Leaf Nodes

    NTX files use a B-tree system to store keys. A B-tree is a balanced, on disk tree who's design minimizes disk access. Interior Nodes and Leaf Nodes share the same structure in an NTX file. The difference is that interior nodes point to other nodes. Leaf nodes point to nothing. Keys in both interior nodes and leaf nodes point to records in a DBF file. Interior nodes have field LeftNodeNo valued which points to the node which points to the keys which are less than the key value in the KeyVal field. There is one more LeftNodeNo value in the node than there are keys. The Last LeftNodeNo points to the node which is greater than the highest key value in the node.

    Leaf nodes have 0 in the LeftNodeNo field.

    NTX Interior Node and Leaf Node Structure
    TypeSizeField NameDescription
    xbShort2NoOfKeysThisNodeThe number of key values in this node. (N)
    Array of xbUShort2offsets[]Array of 
    HeadNode.KeysPerNode +1
    unsigned longs. These values are the offsets (in bytes) of each key in this node, from the beginning of the node.
    charvariableKeyRecsA repeating structure of pointers and keys. See the next table for the KeyRec structure.


    One primary difference between NDX files and NTX files is that NTX files uses an array of offsets on all interior and leaf nodes. Each offset is the byte count from the beginning of the node where each KeyRec will be found. The order of the array of offsets determines the order of keys on a given node. When keys are added or deleted, thus changing the order of the keys on a node, only the order of the offset array is changed. All other key data is not moved. This results in slightly better index performance.

    KeyRec Structure
    TypeSizeField NameDescription
    xbLong4LeftNodeNoThe node number (offset from beginning of file) of the lower node for this key. 0 in Leaf Nodes.
    xbLong4DbfRecNoThe DBF record number for this key. 0 in Interior Nodes.
    charKeyLenKeyValueThe key value.


    For those interested in knowing how the Xbase DBMS manipulates and navigates index files, the following discussion may be helpfull.

    Xbase DBMS navigates through NTX files by using an in-memory chain of nodes of the current location / key in use. It starts by reading the Head Node of the index, which points to the first node of the file. The first node of the file will be a leaf node if the index is small or will be an interior node if the index has more than one leaf node. The first interior node is loaded into memory, added to the node chain and points to the next node to read. The node is made up of one or more keys. If it is a leaf node, the logic looks for a matching key on the node. It continues down the tree, adding the nodes to the in-memory node chain until it reaches the correct node. If it finds a matching key in the leaf node, it returns a XB_FOUND condition. If it doesn't find an exact match in the leaf node, it returns a XB_NOT_FOUND condition and stops on the key which is greater than the search key given.

    NDX Indices

    Chapter Updated 4/12/04

    The objective of this chapter is to provide information regarding the basic concepts of how .NDX index files work in the Xbase environment.

    The information in this chapter has been gathered by searching the internet and by examining the structure of known good NDX indexes.

    NDX Index File Characteristics

  • NDX indices maintain keys in ascending sort order only.

  • NDX indices support unique or non unique keys.

    Unique keys must be unique. The database update routines will fail if an attempt to add a non-unique key is performed.

    Non-unique Keys are not required to be unique, duplicate keys are allowed if the index is created with the XB_NOT_UNIQUE setting. Duplicate keys are stored in record number order.

  • NDX indexes are automatically updated by the Xbase library after the indices are opened.

  • Character keys are left justified and padded on the right with spaces.

  • Numeric keys are stored as eight byte double values.

    NDX File Internals

    NDX files are comprised of two or more 512 byte blocks or nodes of information. There are three types of nodes: Head Nodes, Interior Nodes and Leaf Nodes.

  • The Head Node is the first node in the file starting at position zero (0) and contains information about the NDX file. There is only one Head Node in each index and it always starts at the beginning of the file.

    NDX Header Node
    TypeSizeField NameDescription
    xbLong4StartNodeThis identifies the root node of the index. The Header node is node 0.
    xbLong4Total NodesThis is the count of the total nodes in the index. The count includes the header node.
    xbLong4NoOfKeysTotal number of keys in the index +1
    xbUShort2KeyLenThe index key length
    xbUShort2KeysPerNodeThe maximum number of keys per node
    xbUShort2KeyTypeType of key

    char1UnknownReserved
    char1UniqueUnique indicator
    00 - Not Unique - XB_NON_UNIQUE
    01 - Unique - XB_UNIQUE
    char488KeyExpressionKey expression string
    512Total bytes in node


    The following structure is used by the Xbase NDX routines: struct NdxHeadNode{ xbLong StartNode; /* header node is node 0 */ xbLong TotalNodes; /* includes header node */ xbLong NoOfKeys; /* actual count + 1 */ xbUShort KeyLen; /* length of key data */ xbUShort KeysPerNode; /* max number of keys per node */ xbUShort KeyType; /* 00 = Char, 01 = Numeric */ xbLong KeySize; /* KeyLen + 8 */ char Reserved1; /* Not sure about this one */ char Unique; /* 00 = not unique, 01 = unique*/ char KeyExpression[488]; /* key definition */ }

    Interior and Leaf Nodes

    Interior Nodes and Leaf Nodes share the same structure in an NDX file. The difference between the two types is that interior nodes point to other interior nodes or leaf nodes and leaf nodes point to records in a DBF file. Interior nodes are optional nodes in an NDX file, however if there are more than a few keys in the index there will certainly be one or more interior nodes in the file. There will always be at least one leaf node in the file. Leaf nodes contain DBF record numbers which point to the location of the record in the DBF file.

    Interior nodes have field LeftNodeNo valued which points to the node which points to the keys which are less than the key value in the KeyVal field. There is one more LeftNodeNo value in the node than there are keys. The Last LeftNodeNo points to the node which is greater than the highest key value in the node. Interior nodes have 0 in the value for the DbfRecNo field.

    Leaf nodes have 0 in the LeftNodeNo field but do have a value in the DbfRecNo field which points to a DFB record.

    NDX Interior Node and Leaf Node Structure
    TypeSizeField NameDescription
    xbLong4NoOfKeysThisNodeThe number of key values in this node.
    char508KeyRecA repeating structure of pointers and keys. See the next table for the KeyRec structure.


    KeyRec Structure
    TypeSizeField NameDescription
    xbLong4LeftNodeNoThe node number of the lower node for this key. 0 in Leaf Nodes.
    xbLong4DbfRecNoThe DBF record number for this key. 0 in Interior Nodes.
    charKeyLenKeyValueThe key value.


    For those interested in knowing how the Xbase DBMS manipulates and navigates index files, the following discussion may be helpfull.

    Xbase DBMS navigates through NDX files by using an in-memory chain of nodes of the current location / key in use. It starts by reading the Head Node of the index, which points to the first node of the file. The first node of the file will be a leaf node if the index is small or will be an interior node if the index has more than one leaf node. The first interior node is loaded into memory, added to the node chain and points to the next node to read. The node is made up of one or more keys. If it is a leaf node, the logic looks for a matching key on the node. Otherwise, if it is an interior node, the logic looks at the keys until the search key is greater than or equal to the key in the node and then traverses down the tree to the next node. It continues down the tree, adding the nodes to the in-memory node chain until it reaches the correct leaf node. If it finds a matching key in the leaf node, it returns a XB_FOUND condition. If it doesn't find an exact match in the leaf node, it returns a XB_NOT_FOUND condition and stops on the key which is greater than the search key given.

    Getting Started

    Chapter Updated 8/14/03

    Overview

    Welcome to Xbase DBMS. Xbase DBMS is a collection of specifications, programs, utilities and a C++ class library for manipulating Xbase type datafiles and indices. Xbase has been developed and produced by several people from around the world via the internet.

    The term Xbase is often used used to describe the format of the original DBase, Clipper and Foxbase (.DBF) files. Many vendors support the industry standard Xbase file format and are committed to this technology for many years to come, thus insuring continued support.

    The original purpose of the Xbase library was to provide reliable and economical programming tools to programmers for reading, writing and updating DBF databases, indices and memo fields.


    System Requirements

    To use Xbase DBMS, the following items are needed:

    A computer and C/C++ compiler.

    The original source code is developed on a Linux platform with the GCC public domain C/C++ compiler.

    Xbase DBMS has been successfully ported and runs on Linux, Sun Solaris, OpenVMS, FreeBSD, OS2 and DOS/Windows (Using the large memory model).

    This software is not intended to be used on any system using an SCO operating system.

    Classes and User Interface

    There are six classes in the Xbase library which are available for use in a typical Xbase application program.


    Xbase Classes - Version 1.8.0 and newer
    ClassBasic DescriptionHow UsedOld Class
    Name
    xbXBaseBasic Xbase ClassEvery program gets one of theseXBASE
    xbDbfDatabase and Field classNeed one of these for each open DBF fileDBF
    xbNdxNdx index classNeed one of these for each open NDX indexNDX
    xbNtxNtx index classNeed one of these for each open NTX index
    xbStringString classUsed for handling strings
    xbHtmlHtml generation classNeeded for creating HTML codeHTML


    There are other classes used internally by these Xbase classes, but most application programs need not to be concerned with. These classes are xbStack - used for stack data structures, xbExpn - used for expression logic, and xbDate - used for date manipulation logic.

    Portability, Type Defs and Structures

    To effectively make the Xbase library as portable across platforms as possible, three things occured.

  • First, the software was developed to run and compile on either big endian or little endian computers and store all numeric data in little endian format.

  • Secondly, field types must be consistently defined in each environment. The types.h file defines the xbase data types. To modify the Xbase code base to function in a different (non ported to yet) environment, start by modifying the types.h file for your site and recompile.

  • Thirdly, support for unix automake and autoconf has been to provided support on a wide variety of unices.


    Field Types
    TypeDescription
    xbULongunsigned long int
    xbUShortunsigned short int
    xbShortshort int
    xbLonglong
    xbFloatfloat
    xbDoubledouble
    charchar
    voidvoid
    struct SCHEMAUsed for defining record structures


    Xbase was designed for portability utilizing standard ANSI-C compliant code. If you decide to write updates to the Xbase project, please try to keep your work to standard generic ANSI-C (no special DOS/WINDOWS Calls).

    Compilation Overview

    If you are building the sources on a Linux/Unix platform:

    Download the source
    ./configure
    make
    su
    make install
    exit



    Before compiling the library, you may need to modify the options for your environment. Do "./configure --help" for a list of the current options

    On my server, I had to:
  • Verify the library and associated links were copied from xbase/xbase/.libs into /usr/local/lib
  • Add /usr/local/lib is in /etc/ld.so.conf
  • execute program ldconfig as root to refresh the new libs

    Actual milage at your site may vary.

    Building a program with the Xbase library

    Create a directory for your project:

    cd /home/me
    mkdir MyProject
    cd MyProject
    vi MyProg.cpp

    To use the Xbase classes, include the following header file in the program:

    #include <xbase/xbase.h>

    For more details, check out the sample programs in the xbase/examples directory.

    Compiling and Linking Unix Application Program for v3.0 later

    The install script should have provided specific instructions for your environment on how to link with the xbase library.

    In the Linux environment, assuming that you are using shared libraries, and usr/local/lib has been added to the /etc/ld.so.conf file, and the ldconfig command was executed

    To Compile:
    g++ -c -Wall -I/usr/include -I/usr/src/linux/include-asm-i386 -I/usr/local/include -I/usr/local/xbase myprog.cpp

    To Link Edit:
    g++ -o myprog myprog.o libxbase.so

    Compiling an Application Program with Borland v4.5 C/C++compiler

    With Borland C compiler: bcc -Ic:\xbase\src myprog.cpp -Lc:\xbase\src\xbase.lib

    Getting the latest development version of XBase


    The Xbase project is in an ongoing state of development with new enhancements being added and bug fixes being applied as they are found and the package maintainers have time. There are several programmers from various parts of the world working on Xbase. If you would like to get the latest version of the Xbase library for your project, it is available on sourceforge.net.

    Notes about using the current development library

  • 1 - Library functions may or may not be documented
  • 2 - The library may or may not be stable. This is the development library and is being updated with current code changes. If you are using it, and it does not behave the way you think it should, you may want to drop a note to xdb-devel@lists.sourceforge.net This may sound a little unsettling, but the library is generally stable. It goes through periods of time where it is in a state of flux when major changes are occurring, but for the most part it is probably OK to use.
  • 3 - If you have changes to contribute to the library, mail your updates to xdb-devel@lists.sourceforge.net
    .
