No compatibility issues: this introduces new functionality to JACK and doesn't alter any existing functionality. 2003-09-18 Jack O'Quin * new function jack_set_buffer_size(). Compatibility issues: programs that rely on the buffer size but do not register a callback will fail. Cached output buffer addresses are not valid after the buffer size changes. These rules existed before, but were never enforced. 2003-08-26 Jack O'Quin * typedefs are now defined using the C99 standard fixed-size integer typedefs. These new typedefs are binary compatible with 32-bit platforms, but not 64-bit machines. Programs using printf on these values will get GCC compiler warnings. To suppress the warnings, use the corresponding C99 printf specifications defined in . That header is already implicitly included by , but can also be included explicitly to maintain compatibility with older versions of JACK without messy #ifdef's. Adding explicit casts will also work, but may suppress future warnings you might want to see. * jack_get_sample_rate() now returns jack_nframes_t rather than unsigned long. These are the same on 32-bit machines, but not on 64-bit platforms. 2003-08-13 Jack O'Quin * Many new transport interfaces. It would be silly to list them all here. Please see the new transport control section in the JACK reference manual. * jack_set_transport_info() and jack_engine_takeover_timebase(), (the old timebase master interfaces) now do nothing. Instead, use jack_set_timebase_callback(). 2003-05-09 Jack O'Quin * Added new jack_is_realtime() function. 2003-02-23 Paul Davis * client.c: added deliver_request(). removed all use of strncpy(). changed ClientDynamic to ClientInProcess. 2003-02-10 Taybin Rutkin * client.c (jack_client_new): Checks jack_protocol_version returned from jackd. 2003-02-05 Kai Vehmanen * client.c (jack_set_buffer_size_callback): This function is now deprecated. 2002-12-20 Paul Davis * error.h (jack_set_error_function): added 2002-12-16 Paul Davis * jack.h: added inclusion of pthread.h 2002-12-09 Paul Davis * jack.h (jack_client_new_inprocess): prototype for in-process client creation (not implemented) * jack.h (jack_client_thread_id): added so that clients can easily find out the pthread_t that is running the JACK client code. this turns out to be critical to handling the SIGHUP. 2002-11-15 Paul Davis * client.c: added port alias functions. untested. 2002-11-05 Kai Vehmanen * Created this file.

It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as a normal application), or can they can run within a JACK server (ie. a "plugin"). JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation. %package -n libjack0 Summary: Shared library to access JACK Group: System/Libraries Requires: %{name} = %{version} %description -n libjack0 Shared library to access JACK (Jack Audio Connection Kit). %package -n libjack-devel Summary: Development package for JACK Group: Development/Libraries/C and C++ Requires: libjack0 = %{version} %description -n libjack-devel Files needed for JACK application development (Jack Audio Connection Kit). %package example-clients Summary: Example clients that use JACK Group: Applications/Multimedia Requires: %{name} = %{version} %description example-clients Small example clients that use JACK (Jack Audio Connection Kit). %prep %setup -q %build %configure \ %if %{enable_capabilities} --enable-capabilities \ %if %{strip_jackd} --enable-stripped-jackd \ %endif %endif %if %{enable_tmpdir} --with-default-tmpdir=%{jack_tmpdir} \ %endif %if ! %{oss} --disable-oss \ %endif %if ! %{portaudio} --disable-portaudio \ %endif %if ! %{freebob} --disable-freebob \ %endif %if %{dynsimd} --enable-dynsimd \ %endif --enable-optimize make %install %makeinstall %if %{enable_capabilities} # make jackstart suid root chmod 04755 $RPM_BUILD_ROOT%{_bindir}/jackstart %endif # remove extra install of the documentation rm -rf $RPM_BUILD_ROOT%{_datadir}/%{name}/* %post -n libjack0 -p /sbin/ldconfig %postun -n libjack0 -p /sbin/ldconfig %clean [ "$RPM_BUILD_ROOT" != "/" ] && rm -rf $RPM_BUILD_ROOT %files %defattr(-,root,root) %doc AUTHORS TODO COPYING* %doc %{_mandir}/man1/* %if %{enable_capabilities} %attr(4755, root, root) %{_bindir}/jackstart %doc %{_mandir}/man1/jackstart* %endif %{_bindir}/jackd %{_bindir}/jack_bufsize %{_bindir}/jack_freewheel %{_bindir}/jack_load %{_bindir}/jack_netsource %{_bindir}/jack_samplerate %{_bindir}/jack_session_notify %{_bindir}/jack_transport %{_bindir}/jack_unload %{_bindir}/jack_wait %{_bindir}/alsa_in %{_bindir}/alsa_out %dir %{_libdir}/%{name} %{_libdir}/%{name}/*.so %files -n libjack0 %defattr(-,root,root) %{_libdir}/lib*.so.* %files -n libjack-devel %defattr(-,root,root) %doc doc/reference %{_libdir}/lib*.so %{_libdir}/lib*.la %{_libdir}/%{name}/*.*a %{_libdir}/pkgconfig/* %{_includedir}/%{name} %files example-clients %defattr(-,root,root) %{_bindir}/jackrec %{_bindir}/jack_alias #{_bindir}/jack_bufsize %{_bindir}/jack_connect %{_bindir}/jack_disconnect %{_bindir}/jack_evmon #{_bindir}/jack_freewheel %{_bindir}/jack_impulse_grabber %{_bindir}/jack_lsp #{_bindir}/jack_load %{_bindir}/jack_metro %{_bindir}/jack_midiseq %{_bindir}/jack_midisine %{_bindir}/jack_monitor_client #{_bindir}/jack_netsource #{_bindir}/jack_session_notify %{_bindir}/jack_showtime #{_bindir}/jack_samplerate %{_bindir}/jack_simple_client %{_bindir}/jack_simple_session_client #{_bindir}/jack_transport %{_bindir}/jack_transport_client #{_bindir}/jack_unload #{_bindir}/jack_wait #{_bindir}/alsa_in #{_bindir}/alsa_out %changelog * Sat Mar 27 2010 Rui Nuno Capela -

A better choice is to use a 2.6 kernel. 1) in /usr/src/linux/include/linux/capability.h find these lines #define CAP_INIT_EFF_SET to_cap_t(~0 & ~CAP_TO_MASK(CAP_SETPCAP)) #define CAP_INIT_INH_SET to_cap_t(0) and change them to #define CAP_INIT_EFF_SET to_cap_t(~0) #define CAP_INIT_INH_SET to_cap_t(~0) then recompile your kernel and boot it. (Note that the above lines are from linux 2.4.19; it may be different if you're using a different version) NB: This may expose your system to local denial of service attacks. If it is a shared system or server, you should assess the impact of enabling capabilities in the context of your overall system security requirements. 2) install libcap from ftp://ftp.kernel.org/pub/linux/libs/security/linux-privs/kernel-2.4/ 3) if you're using a journalling filesystem, mount some directory with -t tmpfs and use this with JACK's configure step as the argument to --with-default-tmpdir. 4) use --enable-capabilities with JACK's configure step jack1-0.126.0/m4/0000755000175100001640000000000014170553500012532 5ustar runnerdockerjack1-0.126.0/m4/ltoptions.m40000755000175100001640000003426214170553500015041 0ustar runnerdocker# Helper functions for option handling. -*- Autoconf -*- # # Copyright (C) 2004-2005, 2007-2009, 2011-2015 Free Software # Foundation, Inc. # Written by Gary V.

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) 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. This program 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 General Public License for more details. You should have received a copy of the GNU General Public License along with this program; 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. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. jack1-0.126.0/README.developers0000644000175100001640000001110214170553470015242 0ustar runnerdocker======================================================================= *** README.developers - JACK development practices *** ======================================================================= :Version: $Id$ :Formatting: restructured text, http://docutils.sourceforge.net/rst.html What is this? ----------------------------------------------------------------------- This file is a collection of practices and rules for JACK development. If you have questions, or would like to make changes, raise the issue on jackit-devel (see http://lists.sourceforge.net/lists/listinfo/jackit-devel ). Contents ----------------------------------------------------------------------- - What is this? - Version numbers - Important files for developers - Sending patches - CVS Access - Decision Process Important files for developers ----------------------------------------------------------------------- AUTHORS List of contributors. If you have contributed code, mail Paul Davis to get your name added to the list, or if you have CVS-access, help yourself. :) Also remember to update the per source file copyright statements when committing changes. README.developers This file. TODO A one file mini-bugzilla for JACK developers. Note: this file is no longer actively updated - please use the Mantis bugtracker instead, see http://jackit.sourceforge.net/dev/ . libjack/ChangeLog A list of _all_ changes to the public interface! Version numbers ----------------------------------------------------------------------- JACK's package version ~~~~~~~~~~~~~~~~~~~~~~ JACK's package version is set in configure.in, and consists of major, minor and revision numbers. This version should be updated whenever a non-trivial set of changes is committed to CVS: major version ask on jackit-devel :) minor version incremented when any of the public or internal interfaces are changed revision incremented when implementation-only changes are made Client API versioning ~~~~~~~~~~~~~~~~~~~~~ JACK clients are affected by two interfaces, the JACK Client API (libjack) and the JACK Client Protocol API (interface between jackd and libjack). The former one is versioned using libtool interface versioniong (set in configure.in). This version should be updated whenever a set of changes affecting the interface is committed to CVS: current incremented whenever the public libjack API is changed revision incremented when the libjack implementation is changed age current libjack is both source and binary compatible with libjack interfaces current,current-1,...,current-age Note! It was decided in January 2003 that current interface number will remain as zero until the first stable JACK version is released. JACK Client Protocol is versioned... . Note! All changes that affect the libjack API must be documented in jack/libjack/ChangeLog using the standard ChangeLog style (see GNU developer docs). Sending patches --------------------------------------------------------------------- People without CVS-access ~~~~~~~~~~~~~~~~~~~~~~~~~ Send your patches to jackit-devel. Normally patches are accepted by Paul Davis and/or Jack O'Quin. Either the patch is applied right away, or you get an "ok to me" message, after which other developers with CVS-access can commit the patch. People with CVS-access ~~~~~~~~~~~~~~~~~~~~~~ Trivial changes can be committed without review. For non-trivial changes, you should first send a proposal to jackit-devel and wait for comments. There are no strict approval rules so use of common sense is recommended. ;) Tips for making patches ~~~~~~~~~~~~~~~~~~~~~~~ - test your patch on a clean CVS-checkout - remember to run cvs update before making commits CVS Access ----------------------------------------------------------------------- Contact Paul Davis. Uses of external libraries and other packages ----------------------------------------------------------------------- The main JACK components, jackd and libjack, should only use standard POSIX and ANSI-C services. If use of other interfaces is absolutely needed, it should be made optional in the build process (via a configure switch for example). Other components like example clients and drivers, may rely on other packages, but these dependencies should not affect the main build process. Decision Process ----------------------------------------------------------------------- All non-trivial changes should be discussed on the jackit-devel mailing list. It has been agreed that Paul Davis will make the final decisions based on these discussions. jack1-0.126.0/config/0000755000175100001640000000000014170553503013462 5ustar runnerdockerjack1-0.126.0/config/compile0000755000175100001640000001624514170553503015050 0ustar runnerdocker#! /bin/sh # Wrapper for compilers which do not understand '-c -o'. scriptversion=2012-10-14.11; # UTC # Copyright (C) 1999-2014 Free Software Foundation, Inc. # Written by Tom Tromey . # # 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, or (at your option) # any later version. # # This program 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.

Since fink is not well-integrated with OS X, you must define a bunch of environment variables... export ACLOCAL_FLAGS="-I /sw/share/aclocal" export CFLAGS="-I/sw/include" export CPPFLAGS=$CFLAGS export LDFLAGS="-L/sw/lib" export PKG_CONFIG_PATH="/sw/lib/pkgconfig:/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/opt/local/lib/pkgconfig" Shared memory ============= The system V shared memory is not very reliable on Darwin/MacOSX, so POSIX shared memory API is the preferred default. To override, use... ./configure --disable-posix-shm Jack server audio cycle ======================== On Linux, the jack server audio cycle (jack_run_cycle function) is called in a real-time SCHED_FIFO thread. On Darwin/MacOSX, the jack_run_cycle is directly called inside the CoreAudio audio callback. External client activation =========================== Jack Linux implementation use system fifo/pipe to trigger the clients real-time callback from the server : the first client of an external subgraph is triggered, does it's job and wakes up the next one in the list, and so on until the last client that wakes up the Jack server. This avoid uneeded context switches between the server and clients and thus is more efficient. This Linux implementation works also on Darwin/MacOSX but is not very efficient : audio gliches occur quite frequently. A more efficient system for external client activation has been developed. It use low-level mach messages system to implement fast IPC between the Jack server and the running clients. The Darwin/MacOSX has a very efficient Remote Procedure Call (RPC) implementation that can be used: the Jack server activate each external client in turn in a loop. On the client side, each client uses an additionnal thread only used for the real-time process callback, that will be triggered by the Jack server using this fast RPC mechanism. Real-time threads ================== The Darwin/MacOSX system use a special class of scheduling for real-time threads. Since the server audio cycle is called directly from the CoreAudio callback, there is nothing special to do on the server side. On the client side, the thread used to call the "process" callback from the server is made real-time, using the mach thread API. Compilation and installation ============================= - In the jack/jack folder, you'll have to produce the version.h manually from the version.h.in file ): Edit the version.h.in, replace the JACK_PROTOCOL_VERSION value with the one found in configure.in and save as a new version.h file. You should get something like "#define jack_protocol_version 6" in the file. Several packages need to be installed before compiling Jack : - Fink dlcompat (fink.sourceforge.net) : this package define the dlopen, dlsym... API used in Jack to load drivers and internal clients. The package has to be installed before compiling Jack. - fakepoll is a implementation of the poll function using select. The Fink version of poll does not work correctly, thus the public domain "fakepoll" code has been used instead. It is directly included in the Jack Darwin/MacOSX port. - PortAudio (www.portaudio.com) : PortAudio is a free, cross platform, open-source, audio I/O library. The Jack CoreAudio driver actually is implemented using PortAudio. The PortAudio source code for MacOSX has to be installed and compiled to produce a framework called "PortAudio.framework" that will be used in the Jack link phase. Several targets are available in the Project Builder project : - jackd : build the Jack server ("jackd" executable) - jack framework : build the "Jack.framework" library. - driver : build the PortAudio driver as a "jack_portaudio.so" shared library. - jack_metro : build the "jack_metro" executable. - jack_lsp : build the "jack_lsp" executable. - jack_connect : build the "jack_connect" executable. - jack_disconnect : build the "jack_disconnect" executable. Server, driver and library installation : ----------------------------------------- First copy the Jack.framework in /Library/Framework. Then as root : # cp jack_portaudio /usr/local/lib # cp jackd /usr/local/bin Launching Jack server : ----------------------- By default buffer size is 128 frames and sample rate is 44100. $ jackd -v -R -d coreaudio To setup a 32 frames buffer and a 4800 Hz sample rate : $ jackd -v -R -d coreaudio -p 32 -r 48000 Performances ============= The Darwin/MacOSX implementation is quite efficient: on a G4/867 Mhz, the Jack server can run with a 32 frames buffer size without noticable problems. Known problems or unimplemented features ========================================= - thread cancellation : the pthread API pthread_cancel is not completely available on Darwin/MacOSX. Thread cannot be cancelled in the general case: they must use explicit cancelation points like "pthread_testcancel" (see the "jack_client_thread" function) - xruns detection and report: not implemented. Possible improvements ====================== - The audio driver is built on top of PortAudio. It may be more efficient to directly use the CoreAudio API in order to avoid additional buffer copy and interleaving/disinterleaving operations. - The project uses Project Builder. It would be helpful to work on the autoconf and automake tools as the Linux version. In this case, the macosx/config.h file would have to be removed and generated by configure, and jack/version.h will be generated automatically from jack/version.h.in - Better separation of Linux and Darwin/MacOSX only code.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Originally written for the GNU/Linux operating system, it also supports Mac OS X and various Unix platforms. JACK can connect a number of different client applications to an audio device and also to each other. Most clients are external, running in their own processes as normal applications. JACK also supports internal clients, which run within the \fBjackd\fR process using a loadable "plugin" interface. JACK differs from other audio servers in being designed from the ground up for professional audio work. It focuses on two key areas: synchronous execution of all clients, and low latency operation. For the latest JACK information, please consult the web site, <\fBhttp://www.jackaudio.org\fR>. .SH "OPTIONS" .TP \fB\-d, \-\-driver \fIbackend\fR [\fIbackend\-parameters\fR ] .br Select the audio interface backend. The current list of supported backends is: \fBalsa\fR, \fBcoreaudio\fR, \fBdummy\fR, \fBfreebob\fR, \fBoss\fR \fBsun\fR \fBportaudio\fR and \fB sndio. They are not all available on all platforms. All \fIbackend\-parameters\fR are optional. .TP \fB\-h, \-\-help\fR .br Print a brief usage message describing the main \fBjackd\fR options. These do not include \fIbackend\-parameters\fR, which are listed using the \fB\-\-help\fR option for each specific backend. Examples below show how to list them. .TP \fB\-m, \-\-no\-mlock\fR Do not attempt to lock memory, even if \fB\-\-realtime\fR. .TP \fB\-A \fIdevice\fR, \fB\-A \fIdevice%p\fR, \fB\-A \fIdevice%c\fR .br (Linux-only) A simplified way to add additional audio I/O hardware to an instance of JACK. This argument is actually just a wrapper around the -I (internal client) version, requiring only the name of the ALSA "card" to be used. The name should \fBNOT\fR include any ALSA device access prefix (e.g. "hw:" or "plughw:") but can include a subdevice. If %p is added to the device name, it will be made available for playback only. If %c is added to the device name, it will be made available for capture (recording) only. If neither %p nor %c is added, it will be made available (if possible) for both capture and playback. Although device names may be visible in various places on your system, the file /proc/asound/cards shows them inside square braces. .br Examples: .br -A SB (adds playback and capture for the "SB" device) .br -A Codec,1%c (adds capture (recording) for the 2nd subdevice of the "Codec" device) .br -A MT1a2%p (adds playback the 1st subdevice of the "MT1a2" device) .br The use of -A CARD is actually equivalent to -I foo:zalsa_in/-dhw:CARD \fIand\fR -I CARD:zalsa_out/-dhw:CARD. .br The use of -A CARD%p is actually equivalent to -I CARD:zalsa_out/-dhw:CARD. .br The use of -A CARD%c is actually equivalent to -I CARD:zalsa_in/-dhw:CARD .br .br Note that this option (like -I) can be used regardless of the backend used, so even if you do not use the ALSA backend, you can still add ALSA-supported devices to an instance of JACK. .TP \fB\-I, \-\-internal-client \fIclient-spec\fR .br Load \fIclient-name\fR as an internal client. May be used multiple times. The form of \fIclient-spec\fR can be any of the following: .br client-path .br client-name:client-path .br client-name:client-path/init-string .br client-path/init-string .br The first form will cause jackd to attempt to load the client from a shared object named "client-path" with appropriate suffixes appended. If "client-path" is absolute, jackd will use that (adding a platform appropriate suffix for a shared object). If it is not absolute, jackd will look for "client-path" (with an appropriate suffix) in the same location that drivers and other JACK add-ons are located. .br The second form provides "client-name" as the desired name for the client once loaded, in addition to the "client-path". .br The third form provides an "init-string" in addition to a client name and path, which will be passed to the client's initialization function. .br The final form does not specify the client name, but does include the path to the client's shared object file and an initializations string. .br When invoking JACK from the shell, remember to quote the argument to -I if it includes spaces. .TP \fB\-M, \-\-midi\-bufsize\fR [ \fIevent-count\fR ] Specify the size of the buffer used for MIDI ports. Units are "MIDI events per process() cycle", where an event occupies up to 4 bytes (as most common MIDI events do). The default buffer size is 2048 bytes, which is about 500 MIDI events. Typical values for \fIevent-count\fR will range from 10 to about 1000. Be aware that using very high values along with a large number of ports may cause JACK to fail to start because of the amount of memory that would be required. .TP \fB\-n, \-\-name\fR \fIserver\-name\fR Name this \fBjackd\fR instance \fIserver\-name\fR. If unspecified, this name comes from the \fB$JACK_DEFAULT_SERVER\fR environment variable. It will be "default" if that is not defined. .TP \fB\-p, \-\-port\-max \fI n\fR Set the maximum number of ports the JACK server can manage. The default value is 256. .TP \fB\-\-replace-registry\fR .br Remove the shared memory registry used by all JACK server instances before startup. This should rarely be used, and is intended only for occasions when the structure of this registry changes in ways that are incompatible across JACK versions (which is rare). .TP \fB\-R, \-\-realtime\fR .br Use realtime scheduling (default = true). This is needed for reliable low\-latency performance. On many systems, it requires \fBjackd\fR to run with special scheduler and memory allocation privileges, which may be obtained in several ways. .TP \fB\-r, \-\-no-realtime\fR .br Do not use realtime scheduling. .TP \fB\-P, \-\-realtime\-priority \fIint\fR When running \fB\-\-realtime\fR, set the scheduler priority to \fIint\fR. .TP \fB\-\-silent\fR Silence any output during operation. .TP \fB\-S, \-\-sync\fR .br This option does nothing in this implementation of JACK, but exists for command-line compatibility with JACK2 and possibly other versions. .TP \fB\-T, \-\-temporary\fR Exit once all clients have closed their connections. .TP \fB\-t, \-\-timeout \fIint\fR .br Set client timeout limit in milliseconds. The default is 500 msec. .TP \fB\-X, \-\-slave-driver\fR \fIdriver-name\fR .br Asks the server to load the "slave" driver given by \fIdriver-name\fR. Slave drivers can provide builtin-access to other devices and protocols; the primary slave-driver at this time is the "alsa_midi" one which provides bridging on Linux between native ALSA MIDI and JACK MIDI. .TP \fB\-Z, \-\-nozombies\fR .br Prevent JACK from ever kicking out clients because they were too slow. This cancels the effect any specified timeout value. .TP \fB\-C, \-\-timeout-thres \fItime\fR .br Stop processing clients if JACK cannot complete the process cycle in time (typically caused by CPU overloading or misbehaved clients). The optional \fItime\fR argument specifies the number of miliseconds, during which consectutive process cycles must fail before JACK gives up (if the argument is not given, it defaults to 250). Processing will resume on the next change to the port graph (i.e. a port is added, removed, connected or disconnected) .TP \fB\-u, \-\-unlock\fR .br Unlock libraries GTK+, QT, FLTK, Wine. .TP \fB\-v, \-\-verbose\fR Give verbose output. .TP \fB\-c, \-\-clocksource\fR (\fI h(pet) \fR | \fI s(ystem) \fR) Select a specific wall clock (HPET timer or the system clock). Asking for the now removed cycle-counter timer usiung \fI-c c\fR will result in the use of the system clock. .TP \fB\-V, \-\-version\fR Print the current JACK version number and exit. .SS ALSA BACKEND OPTIONS .TP \fB\-C, \-\-capture\fR [ \fIname\fR ] Provide only capture ports, unless combined with \-D or \-P. Parameterally set capture device name. .TP \fB\-d, \-\-device \fIname\fR .br The ALSA pcm device \fIname\fR to use. If none is specified, JACK will use "hw:0", the first hardware card defined in \fB/etc/modules.conf\fR. .TP \fB\-z, \-\-dither [rectangular,triangular,shaped,none] Set dithering mode. If \fBnone\fR or unspecified, dithering is off. Only the first letter of the mode name is required. .TP \fB\-D, \-\-duplex\fR Provide both capture and playback ports. Defaults to on unless only one of \-P or \-C is specified. .TP \fB\-h, \-\-help\fR Print a brief usage message describing only the \fBalsa\fR backend parameters. .TP \fB\-M, \-\-hwmeter\fR .br Enable hardware metering for devices that support it. Otherwise, use software metering. .TP \fB\-H, \-\-hwmon\fR .br Enable hardware monitoring of capture ports. This is a method for obtaining "zero latency" monitoring of audio input. It requires support in hardware and from the underlying ALSA device driver. When enabled, requests to monitor capture ports will be satisfied by creating a direct signal path between audio interface input and output connectors, with no processing by the host computer at all. This offers the lowest possible latency for the monitored signal. Presently (March 2003), only the RME Hammerfall series and cards based on the ICE1712 chipset (M\-Audio Delta series, Terratec, and others) support \fB\-\-hwmon\fR. In the future, some consumer cards may also be supported by modifying their mixer settings. Without \fB\-\-hwmon\fR, port monitoring requires JACK to read audio into system memory, then copy it back out to the hardware again, imposing the basic JACK system latency determined by the \fB\-\-period\fR and \fB\-\-nperiods\fR parameters. .TP \fB\-i, \-\-inchannels \fIint\fR .br Number of capture channels. Default is maximum supported by hardware. .TP \fB\-n, \-\-nperiods \fIint\fR .br Specify the number of periods of playback latency. In seconds, this corresponds to \fB\-\-nperiods\fR times \fB\-\-period\fR divided by \fB\-\-rate\fR. The default is 2, the minimum allowable. For most devices, there is no need for any other value with the \fB\-\-realtime\fR option. Without realtime privileges or with boards providing unreliable interrupts (like ymfpci), a larger value may yield fewer xruns. This can also help if the system is not tuned for reliable realtime scheduling. For most ALSA devices, the hardware buffer has exactly \fB\-\-period\fR times \fB\-\-nperiods\fR frames. Some devices demand a larger buffer. If so, JACK will use the smallest possible buffer containing at least \fB\-\-nperiods\fR, but the playback latency does not increase. For USB audio devices it is recommended to use \fB\-n 3\fR. Firewire devices supported by FFADO (formerly Freebob) are configured with \fB\-n 3\fR by default. .TP \fB\-o, \-\-outchannels \fIint\fR .br Number of playback channels. Default is maximum supported by hardware. .TP \fB\-P, \-\-playback\fR [ \fIname\fR ] Provide only playback ports, unless combined with \-D or \-C. Optionally set playback device name. .TP \fB\-p, \-\-period \fIint\fR .br Specify the number of frames between JACK \fBprocess()\fR calls. This value must be a power of 2, and the default is 1024. If you need low latency, set \fB\-p\fR as low as you can go without seeing xruns. A larger period size yields higher latency, but makes xruns less likely. The JACK capture latency in seconds is \fB\-\-period\fR divided by \fB\-\-rate\fR. .TP \fB\-r, \-\-rate \fIint\fR Specify the sample rate. The default is 48000. .TP \fB\-S, \-\-shorts .br Try to configure card for 16\-bit samples first, only trying 32\-bits if unsuccessful. Default is to prefer 32\-bit samples. .TP \fB\-s, \-\-softmode\fR .br Ignore xruns reported by the ALSA driver. This makes JACK less likely to disconnect unresponsive ports when running without \fB\-\-realtime\fR. .TP \fB\-X, \-\-midi seq .br Provide bridging between ALSA MIDI and JACK MIDI (using the ALSA sequencer system). All ALSA MIDI clients and MIDI hardware that exist when jackd starts will be represented by JACK MIDI ports. .br The "seq" argument has been retained from older versions of JACK, in part to provide for the possibility of alternate implementations. .SS COREAUDIO BACKEND PARAMETERS .TP \fB\-c \-\-channel\fR Maximum number of channels (default: 2) .TP \fB\-i \-\-channelin\fR Maximum number of input channels (default: 2) .TP \fB\-o \-\-channelout\fR Maximum number of output channels (default: 2) .TP \fB\-C \-\-capture\fR Whether or not to capture (default: true) .TP \fB\-P \-\-playback\fR Whether or not to playback (default: true) .TP \fB\-D \-\-duplex\fR Capture and playback (default: true) .TP \fB\-r \-\-rate\fR Sample rate (default: 44100) .TP \fB\-p \-\-period\fR Frames per period (default: 128). Must be a power of 2. .TP \fB\-n \-\-name\fR Driver name (default: none) .TP \fB\-I \-\-id\fR Audio Device ID (default: 0) .SS DUMMY BACKEND PARAMETERS .TP \fB\-C, \-\-capture \fIint\fR Specify number of capture ports.

A reasonably well\-tuned system with a good sound card and a low\-latency kernel can handle these values reliably. Some can do better. If you get xrun messages, try a larger buffer. Tuning a system for low latency can be challenging.

Any client started without a running JACK server will attempt to start one itself using the command line found in the first line of \fB$HOME/.jackdrc\fR if it exists, or \fB/etc/jackdrc\fR if it does not. If neither file exists, a built\-in default command will be used, including the \fB\-T\fR flag, which causes the server to shut down when all clients have exited. As a transition, this only happens when \fB$JACK_START_SERVER\fR is defined in the environment of the calling process. In the future this will become normal behavior. In either case, defining \fB$JACK_NO_START_SERVER\fR disables this feature. To change where JACK looks for the backend drivers, set \fB$JACK_DRIVER_DIR\fR. \fB$JACK_DEFAULT_SERVER\fR specifies the default server name. If not defined, the string "default" is used. If set in their respective environments, this affects \fBjackd\fR unless its \fB\-\-name\fR parameter is set, and all JACK clients unless they pass an explicit name to \fBjack_client_open()\fR. .SH "SEE ALSO:" .PP .I http://www.jackaudio.org .br The official JACK website with news, docs and a list of JACK clients. .PP .I http://jackaudio.org/email .br The JACK developers' mailing list.

reference manual, built using doxygen. */ /** @page porting-guide Porting JACK The @ref index is designed to be portable to any system supporting the relevant POSIX and C language standards. It currently works with GNU/Linux and Mac OS X on several different processor architectures. This document describes the steps needed to port JACK to another platform, and the methods used to provide portability. - @ref portrequirements - @ref portoverview - @ref portopsys - @ref portcpu - @ref portissues @section portrequirements Requirements - Each platform should build directly from CVS or from a tarball using the GNU @c ./configure tools. Platform-specific toolsets can by used for development, but the GNU tools should at least work for basic distribution and configuration. - For long-term maintainability we want to minimize the use of conditional compilation in source files. - We should provide generic versions of all system-dependent headers, so platforms need only provide those they modify. - In some cases, operating system-specific information must be able to override processor-specific data. @section portoverview Overview JACK relies on two types of platform-specific headers: - @ref portopsys - @ref portcpu OS-specific headers take precedence over CPU-specific headers. The JACK @c configure.host script and its system-dependent header directories were adapted from the @c libstdc++-v3 component of the GNU Compiler Collective, . @section portlang C Language Dependencies JACK is written to conform with C99, as defined in International Standard ISO/IEC 9899:1999. Because many existing compilers do not fully support this standard, some new features should be avoided for portablility reasons. For example, variables should not be declared in the middle of a compound statement, because many compilers still cannot handle that language extension. @section portopsys Operating System Dependencies JACK is written for a POSIX environment compliant with IEEE Std 1003.1-2001, ISO/IEC 9945:2003, including the POSIX Threads Extension (1003.1c-1995) and the Realtime and Realtime Threads feature groups. When some needed POSIX feature is missing on a platform, the preferred solution is to provide a substitute, as with the @c fakepoll.c implementation for Mac OS X. Whenever possible, OS dependencies should be auto-detected by @c configure. Sometimes they can be isolated in OS-specific header files, found in subdirectories of @c config/os and referenced with a @c name. If conditional compilation must be used in mainline platform-independent code, avoid using the system name. Instead, @c \#define a descriptive name in @c , and test it like this: @code \#ifdef JACK_USE_MACH_THREADS allocate_mach_serverport(engine, client); client->running = FALSE; \#endif @endcode Be sure to place any generic implementation alternative in the @c \#else or use an @c \#ifndef, so no other code needs to know your conditional labels. @section portissues Issues Not Addressed - Cross-compilation has not been tested, or even thought through in much detail. The @a host is the system on which JACK will run. This may differ from the @a build system doing the compilation. These are selected using the standard @c ./configure options @c --host and @c --build. Usually, @c ./config.guess can print the appropriate canonical name for any system on which it runs. - Platform-specific build tools like Apple's Project Builder are not well-supported. */ jack1-0.126.0/doc/transport.dox0000644000175100001640000002231114170553470015534 0ustar runnerdocker/* * This file documents the JACK transport design. It is part of the * JACK reference manual, built using doxygen. */ /** @page transport-design JACK Transport Design The @ref index provides simple transport interfaces for starting, stopping and repositioning a set of clients. This document describes the overall design of these interfaces, their detailed specifications are in - @ref requirements - @ref overview - @ref timebase - @ref transportcontrol - @ref transportclients - @ref compatibility - @ref issues @section requirements Requirements - We need sample-level accuracy for transport control. This implies that the transport client logic has to be part of the realtime process chain. - We don't want to add another context switch. So, the transport client logic has to run in the context of the client's process thread. To avoid making an extra pass through the process graph, no transport changes take effect until the following process cycle. That way, the transport info is stable throughout each cycle. - We want to allow multiple clients to change the transport state. This is mostly a usability issue. Any client can start or stop playback, or seek to a new location. The user need not switch windows to accomplish these tasks. - We want a way for clients with heavyweight state to sync up when the user presses "play", before the transport starts rolling. - We want to provide for ongoing binary compatibility as the transport design evolves. @section overview Overview The former transport master role has been divided into two layers: - @ref timebase - counting beats, frames, etc. on every cycle. - @ref transportcontrol - start, stop and reposition the playback. Existing transport clients continue to work in compatibility mode. But, old-style timebase masters will no longer control the transport. @section timebase Timebase Master The timebase master continuously updates extended position information, counting beats, timecode, etc. Without this extended information, there is no need for this function. There is at most one master active at a time. If no client is registered as timebase master, frame numbers will be the only position information available. The timebase master registers a callback that updates position information while the transport is rolling. Its output affects the following process cycle. This function is called immediately after the process callback in the same thread whenever the transport is rolling, or when any client has set a new position in the previous cycle. The first cycle after jack_set_timebase_callback() is also treated as a new position, or the first cycle after jack_activate() if the client had been inactive. @code typedef int (*JackTimebaseCallback)(jack_transport_state_t state, jack_nframes_t nframes, jack_position_t *pos, int new_pos, void *arg); @endcode When a new client takes over, the former timebase callback is no longer called. Taking over the timebase may be done conditionally, in which case the takeover fails when there is a master already. The existing master can release it voluntarily, if desired. @code int jack_set_timebase_callback (jack_client_t *client, int conditional, JackTimebaseCallback timebase_callback, void *arg); int jack_release_timebase(jack_client_t *client); @endcode If the timebase master releases the timebase or exits the JACK graph for any reason, the JACK engine takes over at the start of the next process cycle. The transport state does not change. If rolling, it continues to play, with frame numbers as the only available position information. @section transportcontrol Transport Control The JACK engine itself manages stopping and starting of the transport. Any client can make transport control requests at any time. These requests take effect no sooner than the next process cycle, sometimes later. The transport state is always valid, initially it is ::JackTransportStopped. @code void jack_transport_start (jack_client_t *client); void jack_transport_stop (jack_client_t *client); @endcode @subsection slowsyncclients Slow-sync clients The engine handles polling of slow-sync clients. When someone calls jack_transport_start(), the engine resets the poll bits and changes to a new state, ::JackTransportStarting. The @a sync_callback function for each slow-sync client will be invoked in the JACK process thread while the transport is starting. If it has not already done so, the client needs to initiate a seek to reach the starting position. The @a sync_callback returns false until the seek completes and the client is ready to play. When all slow-sync clients are ready, the state changes to ::JackTransportRolling. @code typedef int (*JackSyncCallback)(jack_transport_state_t state, jack_position_t *pos, void *arg); @endcode This callback is a realtime function that runs in the JACK process thread. @code int jack_set_sync_callback (jack_client_t *client, JackSyncCallback sync_callback, void *arg); @endcode Clients that don't declare a @a sync_callback are assumed to be ready immediately, any time the transport wants to start. If a client no longer requires slow-sync processing, it can set its @a sync_callback to NULL. @code int jack_set_sync_timeout (jack_client_t *client, jack_time_t usecs); @endcode There must be a @a timeout to prevent unresponsive slow-sync clients from completely halting the transport mechanism. Two seconds is the default. When this @a timeout expires, the transport will start rolling, even if some slow-sync clients are still unready. The @a sync_callback for these clients continues being invoked, giving them an opportunity to catch up. @subsection repositioning Repositioning @code int jack_transport_reposition (jack_client_t *client, jack_position_t *pos); int jack_transport_locate (jack_client_t *client, jack_nframes_t frame); @endcode These request a new transport position. They can be called at any time by any client. Even the timebase master must use them. If the request is valid, it goes into effect in two process cycles. If there are slow-sync clients and the transport is already rolling, it will enter the ::JackTransportStarting state and begin invoking their @a sync_callbacks until ready. @subsection transportstatetransitiondiagram Transport State Transition Diagram @image html fsm.png "Transport State Transition Diagram" @image latex fsm.eps "Transport State Transition Diagram" @section transportclients Transport Clients Transport clients were formerly known as "transport slaves". We want to make it easy for almost every JACK client to be a transport client. @code jack_transport_state_t jack_transport_query (jack_client_t *client, jack_position_t *pos); @endcode This function can be called from any thread. If called from the process thread, @a pos corresponds to the first frame of the current cycle and the state returned is valid for the entire cycle. @section compatibility Compatibility During the transition period we will support the old-style interfaces in compatibility mode as deprecated interfaces. This compatibility is not 100%, there are limitations. The main reasons for doing this are: - facilitate testing with clients that already have transport support - provide a clean migration path, so application developers are not discouraged from supporting the transport interface These deprecated interfaces continue to work: @code typedef struct jack_transport_info_t; void jack_get_transport_info (jack_client_t *client, jack_transport_info_t *tinfo); @endcode Unfortunately, the old-style timebase master interface cannot coexist cleanly with such new features as jack_transport_locate() and slow-sync clients. So, these interfaces are only present as stubs: @code void jack_set_transport_info (jack_client_t *client, jack_transport_info_t *tinfo); int jack_engine_takeover_timebase (jack_client_t *); @endcode For compatibility with future changes, it would be good to avoid structures entirely. Nevertheless, the jack_position_t structure provides a convenient way to collect timebase information in several formats that clearly all refer to a single moment. To minimize future binary compatibility problems, this structure has some padding at the end, making it possible to extend it without necessarily breaking compatibility. New fields can be allocated from the padding area, with access controlled by newly defined valid bits, all of which are currently forced to zero. That allows the structure size and offsets to remain constant. @section issues Issues Not Addressed This design currently does not address several issues. This means they will probably not be included in JACK release 1.0. - variable speed - reverse play - looping */ jack1-0.126.0/doc/mainpage.dox0000644000175100001640000001604314170553470015266 0ustar runnerdocker/* * This is the main page of the JACK reference manual, built using * doxygen. */ /** @mainpage JACK Audio Connection Kit @section intro Introduction JACK is a low-latency audio server, written for any operating system that is reasonably POSIX compliant. It currently exists for Linux, OS X, Solaris, FreeBSD and Windows. It can connect several client applications to an audio device, and allow them to share audio with each other. Clients can run as separate processes like normal applications, or within the JACK server as "plugins". JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation. @see @section jack_overview JACK Overview Traditionally it has been hard if not impossible to write audio applications that can share data with each other. In addition, configuring and managing audio interface hardware has often been one of the most complex aspect of writing audio software. JACK changes all this by providing an API that does several things: 1. provides a high level abstraction for programmers that removes the audio interface hardware from the picture and allows them to concentrate on the core functionality of their software. 2. allows applications to send and receive audio data to/from each other as well as the audio interface. There is no difference in how an application sends or receives data regardless of whether it comes from/goes to another application or an audio interface. For programmers with experience of several other audio APIs such as PortAudio, Apple's CoreAudio, Steinberg's VST and ASIO as well as many others, JACK presents a familiar model: your program provides a "callback" function that will be executed at the right time. Your callback can send and receive data as well as do other signal processing tasks. You are not responsible for managing audio interfaces or threading, and there is no "format negotiation": all audio data within JACK is represented as 32 bit floating point values. For those with experiences rooted in the Unix world, JACK presents a somewhat unfamiliar API. Most Unix APIs are based on the read/write model spawned by the "everything is a file" abstraction that Unix is rightly famous for. The problem with this design is that it fails to take the realtime nature of audio interfaces into account, or more precisely, it fails to force application developers to pay sufficient attention to this aspect of their task. In addition, it becomes rather difficult to facilitate inter-application audio routing when different programs are not all running synchronously. Using JACK within your program is very simple, and typically consists of just: - calling @ref jack_client_open() to connect to the JACK server. - registering "ports" to enable data to be moved to and from your application. - registering a "process callback" which will be called at the right time by the JACK server. - telling JACK that your application is ready to start processing data. There is a lot more that you can do with JACK's interfaces, but for many applications, this is all that is needed. The @ref simple_client.c example demonstrates a complete (simple!) JACK application that just copies the signal arriving at its input port to its output port. Similarly, @ref inprocess.c shows how to write an internal client "plugin" that runs within the JACK server process. @section reference Reference The JACK programming interfaces are described in several header files. We present them here broken into useful categories to make the API a little clearer: - @ref ClientFunctions - @ref ClientCallbacks - @ref ClientThreads - @ref ServerControl - @ref PortFunctions - @ref PortSearching - @ref LatencyFunctions - @ref TimeFunctions - @ref TransportControl - @ref ErrorOutput - @ref NonCallbackAPI - @ref MIDIAPI - @ref SessionClientFunctions - @ref WeakLinkage - @ref ControlAPI - @ref Metadata The full API is described in: - @ref jack.h "" is the main JACK interface. - @ref statistics.h "" provides interfaces for monitoring the performance of a running JACK server. - @ref intclient.h "" allows loading and unloading JACK internal clients. - @ref ringbuffer.h "" defines a simple API for using lock-free ringbuffers. These are a good way to pass data between threads, when streaming realtime data to slower media, like audio file playback or recording. - @ref transport.h "" defines a simple transport control mechanism for starting, stopping and repositioning clients. This is described in the @ref transport-design document. - @ref types.h "" defines the main JACK data types. - @ref thread.h "" functions standardize thread creation for JACK and its clients. - @ref midiport.h "" functions to handle reading and writing of MIDI data to a port - @ref session.h "" functions that form the JACK session API - @ref control.h "" the API for starting and controlling a JACK server - @ref metadata.h "" the API for managing metadata about objects within JACK (clients and ports) In addition, the tools directory provides numerous examples of simple JACK clients that nevertheless use the API to do something useful. It includes - a metronome. - a recording client that can capture any number of channels from any JACK sources and store them as an audio file. - command line clients to control the transport mechanism, change the buffer size and more. - commands to load and unload JACK internal clients. - tools for checking the status of a running JACK system. and many more. @section porting Porting JACK is designed to be portable to any system supporting the relevant POSIX and ANSI C standards. It currently runs under GNU/Linux, Mac OS X and Berkeley Unix on several different processor architectures. If you want to port JACK to another platform, please read the @ref porting-guide document. @section license License Copyright (C) 2001-2019 by Paul Davis, Stephane Letz, Jack O'Quinn, Torben Hohn, Filipe Coelho and others.

Normally, if an application uses a new * feature in a library/API, it is unable to run on * earlier versions of the library/API that do not * support that feature. Such applications would either * fail to launch or crash when an attempt to use the * feature was made. This problem cane be solved using * weakly-linked symbols. * * When a symbol in a framework is defined as weakly * linked, the symbol does not have to be present at * runtime for a process to continue running. The static * linker identifies a weakly linked symbol as such in * any code module that references the symbol. The * dynamic linker uses this same information at runtime * to determine whether a process can continue * running. If a weakly linked symbol is not present in * the framework, the code module can continue to run as * long as it does not reference the symbol. However, if * the symbol is present, the code can use it normally. * * (adapted from: http://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html) * * A concrete example will help. Suppose that someone uses a version * of a JACK client we'll call "Jill". Jill was linked against a version * of JACK that contains a newer part of the API (say, jack_set_latency_callback()) * and would like to use it if it is available. * * When Jill is run on a system that has a suitably "new" version of * JACK, this function will be available entirely normally. But if Jill * is run on a system with an old version of JACK, the function isn't * available. * * With normal symbol linkage, this would create a startup error whenever * someone tries to run Jill with the "old" version of JACK. However, functions * added to JACK after version 0.116.2 are all declared to have "weak" linkage * which means that their abscence doesn't cause an error during program * startup. Instead, Jill can test whether or not the symbol jack_set_latency_callback * is null or not. If its null, it means that the JACK installed on this machine * is too old to support this function. If its not null, then Jill can use it * just like any other function in the API. For example: * * \code * if (jack_set_latency_callback) { * jack_set_latency_callback (jill_client, jill_latency_callback, arg); * } * \endcode * * However, there are clients that may want to use this approach to parts of the * the JACK API that predate 0.116.2. For example, they might want to see if even * really old basic parts of the API like jack_client_open() exist at runtime. * * Such clients should include before any other JACK header. * This will make the \b entire JACK API be subject to weak linkage, so that any * and all functions can be checked for existence at runtime. It is important * to understand that very few clients need to do this - if you use this * feature you should have a clear reason to do so. * * */ #ifdef __APPLE__ #define WEAK_ATTRIBUTE weak_import #else #define WEAK_ATTRIBUTE __weak__ #endif #ifndef JACK_OPTIONAL_WEAK_EXPORT /* JACK_OPTIONAL_WEAK_EXPORT needs to be a macro which expands into a compiler directive.

The driver should set this to be the interval it expects to elapse between returning from the `wait' function. if set to zero, it implies that the driver does not expect regular periodic wakeups. jack_time_t period_usecs; The driver should set this within its "wait" function to indicate the UST of the most recent determination that the engine cycle should run. it should not be set if the "extra_fd" argument of the wait function is set to a non-zero value. jack_time_t last_wait_ust; These are not used by the driver. They should not be written to or modified in any way void *handle; struct _jack_internal_client *internal_client; This should perform any cleanup associated with the driver. it will be called when jack server process decides to get rid of the driver. in some systems, it may not be called at all, so the driver should never rely on a call to this. it can set it to NULL if it has nothing do do. void (*finish)(struct _jack_driver *); The JACK engine will call this when it wishes to attach itself to the driver. the engine will pass a pointer to itself, which the driver may use in anyway it wishes to. the driver may assume that this is the same engine object that will make `wait' calls until a `detach' call is made. JackDriverAttachFunction attach; The JACK engine will call this when it is finished using a driver. JackDriverDetachFunction detach; The JACK engine will call this when it wants to wait until the driver decides that its time to process some data. the driver returns a count of the number of audioframes that can be processed. it should set the variable pointed to by `status' as follows: zero: the wait completed normally, processing may begin negative: the wait failed, and recovery is not possible positive: the wait failed, and the driver stopped itself. a call to `start' will return the driver to a correct and known state. the driver should also fill out the `delayed_usecs' variable to indicate any delay in its expected periodic execution. for example, if it discovers that its return from poll(2) is later than it expects it to be, it would place an estimate of the delay in this variable. the engine will use this to decide if it plans to continue execution. JackDriverWaitFunction wait; The JACK engine will call this to ask the driver to move data from its inputs to its output port buffers. it should return 0 to indicate successful completion, negative otherwise. This function will always be called after the wait function (above). JackDriverReadFunction read; The JACK engine will call this to ask the driver to move data from its input port buffers to its outputs. it should return 0 to indicate successful completion, negative otherwise. this function will always be called after the read function (above). JackDriverWriteFunction write; The JACK engine will call this after the wait function (above) has been called, but for some reason the engine is unable to execute a full "cycle". the driver should do whatever is necessary to keep itself running correctly, but cannot reference ports or other JACK data structures in any way. JackDriverNullCycleFunction null_cycle; The engine will call this when it plans to stop calling the `wait' function for some period of time. the driver should take appropriate steps to handle this (possibly no steps at all). NOTE: the driver must silence its capture buffers (if any) from within this function or the function that actually implements the change in state. JackDriverStopFunction stop; The engine will call this to let the driver know that it plans to start calling the `wait' function on a regular basis. the driver should take any appropriate steps to handle this (possibly no steps at all). NOTE: The driver may wish to silence its playback buffers (if any) from within this function or the function that actually implements the change in state. JackDriverStartFunction start; The engine will call this to let the driver know that some client has requested a new buffer size. The stop function will be called prior to this, and the start function after this one has returned.

Note that this is asymmetric. Sample ranges for signed integer, 2's complement values are -(2^(N-1) to +(2^(N-1)-1) Complications ------------- If we use +2^(N-1) for the scaling factors, we run into a problem: if we start with a normalized float value of -1.0, scaling to 24 bits would give -8388608 (-2^23), which is ideal. But with +1.0, we get +8388608, which is technically out of range.

This machine is generally designated as the slave machine. jacknet_client is a jack application that shall be run from another computer with the ip adress of the other machine as argument. This machine is generalled designated as the master machine. || PREREQUISITES Two machines with a _good_ network connection between them. A Jack (http://jackit.sf.net) source package. || INSTALLATION: compile with scons jack_source_dir='path/to/jack-src' this creates jack_net.so. copy this to /lib/jack/drivers or wherever jack looks for driver.so`s it also creates jacknet_client. a normal program. if you build on OSX you need to add with_alsa=0 || USAGE The programs will open a bidirectional connection between the two machines (using UDP). Exposing a stereopair both ways. The udpsync_source needs the slave machine as a parameter. The alsa-client is a nice thing also, it makes a not jack related alsa-card available for capturing under jack. Best performance is achieved if connecting the machines with an XOVER cable, omitting switches / hubs / other nasty things. || KNOWN ISSUES While running with full duplex, utilizing the slave machine as an outboard effect it seems very hard (atleast with my network with a cheap switch inbetween) to use buffers below 512. Sometimes 256 is usable for a while. While connecting ports on the slave side it is very prone to crash if the buffers are small. The jitter of a wlan network is a little too hard for the current sync code. A delay locked loop might be used soon. There is always atleast one buffers delay if a port is routed back through the connection. This is a design issue that might be hard to remedy. || LICENSE this is free software under the GPL license, see the file COPYING. jack1-0.126.0/drivers/freebob/0000755000175100001640000000000014170553503015277 5ustar runnerdockerjack1-0.126.0/drivers/freebob/Makefile.in0000644000175100001640000005274014170553503017354 0ustar runnerdocker# Makefile.in generated by automake 1.15.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2017 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@ VPATH = @srcdir@ am__is_gnu_make = { \ if test -z '$(MAKELEVEL)'; then \ false; \ elif test -n '$(MAKE_HOST)'; then \ true; \ elif test -n '$(MAKE_VERSION)' && test -n '$(CURDIR)'; then \ true; \ else \ false; \ fi; \ } am__make_running_with_option = \ case $${target_option-} in \ ?) ;; \ *) echo "am__make_running_with_option: internal error: invalid" \ "target option '$${target_option-}' specified" >&2; \ exit 1;; \ esac; \ has_opt=no; \ sane_makeflags=$$MAKEFLAGS; \ if $(am__is_gnu_make); then \ sane_makeflags=$$MFLAGS; \ else \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ bs=\\; \ sane_makeflags=`printf '%s\n' "$$MAKEFLAGS" \ | sed "s/$$bs$$bs[$$bs $$bs ]*//g"`;; \ esac; \ fi; \ skip_next=no; \ strip_trailopt () \ { \ flg=`printf '%s\n' "$$flg" | sed "s/$$1.*$$//"`; \ }; \ for flg in $$sane_makeflags; do \ test $$skip_next = yes && { skip_next=no; continue; }; \ case $$flg in \ *=*|--*) continue;; \ -*I) strip_trailopt 'I'; skip_next=yes;; \ -*I?*) strip_trailopt 'I';; \ -*O) strip_trailopt 'O'; skip_next=yes;; \ -*O?*) strip_trailopt 'O';; \ -*l) strip_trailopt 'l'; skip_next=yes;; \ -*l?*) strip_trailopt 'l';; \ -[dEDm]) skip_next=yes;; \ -[JT]) skip_next=yes;; \ esac; \ case $$flg in \ *$$target_option*) has_opt=yes; break;; \ esac; \ done; \ test $$has_opt = yes am__make_dryrun = (target_option=n; $(am__make_running_with_option)) am__make_keepgoing = (target_option=k; $(am__make_running_with_option)) pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = drivers/freebob ACLOCAL_M4 = $(top_srcdir)/aclocal.m4 am__aclocal_m4_deps = $(top_srcdir)/m4/libtool.m4 \ $(top_srcdir)/m4/ltoptions.m4 $(top_srcdir)/m4/ltsugar.m4 \ $(top_srcdir)/m4/ltversion.m4 $(top_srcdir)/m4/lt~obsolete.m4 \ $(top_srcdir)/acinclude.m4 $(top_srcdir)/configure.ac am__configure_deps = $(am__aclocal_m4_deps) $(CONFIGURE_DEPENDENCIES) \ $(ACLOCAL_M4) DIST_COMMON = $(srcdir)/Makefile.am $(noinst_HEADERS) \ $(am__DIST_COMMON) mkinstalldirs = $(install_sh) -d CONFIG_HEADER = $(top_builddir)/config.h CONFIG_CLEAN_FILES = CONFIG_CLEAN_VPATH_FILES = am__vpath_adj_setup = srcdirstrip=`echo "$(srcdir)" | sed 's|.|.|g'`; am__vpath_adj = case $$p in \ $(srcdir)/*) f=`echo "$$p" | sed "s|^$$srcdirstrip/||"`;; \ *) f=$$p;; \ esac; am__strip_dir = f=`echo $$p | sed -e 's|^.*/||'`; am__install_max = 40 am__nobase_strip_setup = \ srcdirstrip=`echo "$(srcdir)" | sed 's/[].[^$$\\*|]/\\\\&/g'` am__nobase_strip = \ for p in $$list; do echo "$$p"; done | sed -e "s|$$srcdirstrip/||" am__nobase_list = $(am__nobase_strip_setup); \ for p in $$list; do echo "$$p $$p"; done | \ sed "s| $$srcdirstrip/| |;"' / .*\//!s/ .*/ ./; s,\( .*\)/[^/]*$$,\1,' | \ $(AWK) 'BEGIN { files["."] = "" } { files[$$2] = files[$$2] " " $$1; \ if (++n[$$2] == $(am__install_max)) \ { print $$2, files[$$2]; n[$$2] = 0; files[$$2] = "" } } \ END { for (dir in files) print dir, files[dir] }' am__base_list = \ sed '$$!N;$$!N;$$!N;$$!N;$$!N;$$!N;$$!N;s/\n/ /g' | \ sed '$$!N;$$!N;$$!N;$$!N;s/\n/ /g' am__uninstall_files_from_dir = { \ test -z "$$files" \ || { test !

Jan 30, 2004: Johnny Petrantoni: first code of the coreaudio driver, based on portaudio driver by Stephane Letz. Feb 02, 2004: Johnny Petrantoni: fixed null cycle, removed double copy of buffers in AudioRender, the driver works fine (tested with Built-in Audio and Hammerfall RME), but no cpu load is displayed. Feb 03, 2004: Johnny Petrantoni: some little fix. Feb 03, 2004: Stephane Letz: some fix in AudioRender.cpp code. Feb 03, 2004: Johnny Petrantoni: removed the default device stuff (useless, in jackosx, because JackPilot manages this behavior), the device must be specified. and all parameter must be correct. Feb 04, 2004: Johnny Petrantoni: now the driver supports interfaces with multiple interleaved streams (such as the MOTU 828). Nov 05, 2004: S.Letz: correct management of -I option for use with JackPilot. Nov 15, 2004: S.Letz: Set a default value for deviceID. Nov 30, 2004: S.Letz: In coreaudio_driver_write : clear to avoid playing dirty buffers when the client does not produce output anymore. Dec 05, 2004: S.Letz: XRun detection Dec 09, 2004: S.Letz: Dynamic buffer size change Dec 23, 2004: S.Letz: Correct bug in dynamic buffer size change : update period_usecs Jan 20, 2005: S.Letz: Almost complete rewrite using AUHAL. May 20, 2005: S.Letz: Add "systemic" latencies management. Jun 06, 2005: S.Letz: Remove the "-I" parameter, change the semantic of "-n" parameter : -n (driver name) now correctly uses the PropertyDeviceUID (persistent accross reboot...) as the identifier for the used coreaudio driver. Jun 14, 2005: S.Letz: Since the "-I" parameter is not used anymore, rename the "systemic" latencies management parametes "-I" and "-O" like for the ALSA driver. Aug 16, 2005: S.Letz: Remove get_device_id_from_num, use get_default_device instead. If the -n option is not used or the device name cannot be found, the default device is used. Note: the default device can be used only if both default input and default output are the same. Dec 19, 2005: S.Letz: Add -d option (display_device_names). Apri 7, 2006: S.Letz: Synchronization with the jackdmp coreaudio driver version: improve half-duplex management. May 17, 2006: S.Letz: Minor fix in driver_initialize. May 18, 2006: S.Letz: Document sample rate default value. May 31, 2006: S.Letz: Apply Rui patch for more consistent driver parameter naming. Dec 04, 2007: S.Letz: Fix a bug in sample rate management (occuring in particular with "aggregate" devices). Dec 05, 2007: S.Letz: Correct sample_rate management in Open. Better handling in sample_rate change listener. */ #include #include #include "engine.h" #include "coreaudio_driver.h" const int CAVersion = 3; //#define PRINTDEBUG 1 static void JCALog (char *fmt, ...) { #ifdef PRINTDEBUG va_list ap;

Grame Research Laboratory, 9, rue du Garet 69001 Lyon - France grame@rd.grame.fr 02-09-03 : Modify jack port naming : add the name of the used driver Add the -n option to load a specific driver using it's name 04-09-03 : Correct bug in -n option management : input and ouput have to be treated separately 08-09-03 : More robust driver loading code : new portaudio_load_default and portaudio_load_driver functions. 24-09-03 : Does not tries to load default device if the required one is not found, returns and error. 14-10-03 : After jack port name size extension, does not use fixed length for CoreAudio driver name anymore 09-01-04 : Handle different value for channel in and channel out (using -i and -o) 12-01-04 : Connect port names (inverse "in" and "out") 13-01-04 : Correct the length of jack port : use JACK_PORT_NAME_SIZE 22-03-04 : Remove jack_init_time, rename input and ouput ports using "capture" and "playback" 10-11-04 : S. Letz: Add management of -I option for use with JackPilot. 17-11-04 : S. Letz: Better debug code. 03-02-05 : S. Letz: fix several driver detection bugs on OSX. 06-08-05 : S.Letz: Remove the "-I" parameter, change the semantic of "-n" parameter on OSX : -n (driver name) now correctly uses the PropertyDeviceUID (persistent accross reboot...) as the identifier for the used coreaudio driver. */ #include #include #include #include #include "engine.h" #include "portaudio_driver.h" #ifdef JACK_USE_MACH_THREADS #include #include static OSStatus get_device_name_from_id (AudioDeviceID id, char name[60]) { UInt32 size = sizeof(char) * 60;

[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.

Typically, this means "sys.argv[1:]". shortopts is the string of option letters that the script wants to recognize, with options that require an argument followed by a colon (i.e., the same format that Unix getopt() uses). If specified, longopts is a list of strings with the names of the long options which should be supported. The leading '--' characters should not be included in the option name. Options which require an argument should be followed by an equal sign ('='). The return value consists of two elements: the first is a list of (option, value) pairs; the second is the list of program arguments left after the option list was stripped (this is a trailing slice of the first argument). Each option-and-value pair returned has the option as its first element, prefixed with a hyphen (e.g., '-x'), and the option argument as its second element, or an empty string if the option has no argument. The options occur in the list in the same order in which they were found, thus allowing multiple occurrences. Long and short options may be mixed.
