In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Compiling

Once you have the distribution, on UNIX, unpack it using gzip and tar. That will create a new directory 'iperf-<version#>' with the source files and documentation.

Iperf compiles cleanly on many systems including Linux, SGI IRIX, HP-UX, Solaris, AIX, and Cray UNICOS. Use 'make' to configure for your OS and compile the source code. 


gunzip -c iperf-<version>.tar.gz | tar -xvf -
cd iperf-<version>
./configure
make
To install iperf, use 'make install', which will ask you where to install it. To recompile, the easiest way is to start over. Do 'make distclean' then './configure; make'. See the Makefile for more options.

If you have problems, please report them to dast@nlanr.net and we will try to fix them quickly.

Features

  • TCP
    • Measure bandwidth
    • Report MSS/MTU size and observed read sizes.
    • Support for TCP window size via socket buffers.
    • Multi-threaded if pthreads or Win32 threads are available. Client and server can have multiple simultaneous connections.

    • Multicast capable
    • Multi-threaded if pthreads are available. Client and server can have multiple simultaneous connections. (This doesn't work in Windows.)
  • Where appropriate, options can be specified with K (kilo-) and M (mega-) suffices. So 128K instead of 131072 bytes.
  • Can run for specified time, rather than a set amount of data to transfer.
  • Picks the best units for the size of data being reported.
  • Server handles multiple connections, rather than quitting after a single test.
  • Print periodic, intermediate bandwidth, jitter, and loss reports at specified intervals.
  • Run the server as a daemon (Check out Nettest for running it as a secure daemon).
  • Run the server as a Windows NT Service
  • Use representative streams to test out how link layer compression affects your achievable bandwidth.

 
Command line option Environment variable option Description
Client and Server options
-f, --format [bkmaBKMA] $IPERF_FORMAT A letter specifying the format to print bandwidth numbers in. Supported formats are  
    'b' = bits/sec            'B' = Bytes/sec
    'k' = Kbits/sec           'K' = KBytes/sec
    'm' = Mbits/sec           'M' = MBytes/sec
    'g' = Gbits/sec           'G' = GBytes/sec
    'a' = adaptive bits/sec   'A' = adaptive Bytes/sec
The adaptive formats choose between kilo- and mega- as appropriate. Fields other than bandwidth always print bytes, but otherwise follow the requested format. Default is 'a'. 
NOTE: here Kilo = 1024, Mega = 1024^2 and Giga = 1024^3 when dealing with bytes. Commonly in networking, Kilo = 1000, Mega = 1000^2, and Giga = 1000^3 so we use this when dealing with bits. If this really bothers you, use -f b and do the math.
-i, --interval # $IPERF_INTERVAL Sets the interval time in seconds between periodic bandwidth, jitter, and loss reports. If non-zero, a report is made every interval seconds of the bandwidth since the last report. If zero, no periodic reports are printed. Default is zero.
-l, --len #[KM] $IPERF_LEN The length of buffers to read or write. Iperf works by writing an array of len bytes a number of times. Default is 8 KB for TCP, 1470 bytes for UDP. Note for UDP, this is the datagram size and needs to be lowered when using IPv6 addressing to 1450 or less to avoid fragmentation. See also the -n and -t options.
-m, --print_mss $IPERF_PRINT_MSS Print the reported TCP MSS size (via the TCP_MAXSEG option) and the observed read sizes which often correlate with the MSS. The MSS is usually the MTU - 40 bytes for the TCP/IP header. Often a slightly smaller MSS is reported because of extra header space from IP options. The interface type corresponding to the MTU is also printed (ethernet, FDDI, etc.). This option is not implemented on many OSes, but the read sizes may still indicate the MSS.
-p, --port # $IPERF_PORT The server port for the server to listen on and the client to connect to. This should be the same in both client and server. Default is 5001, the same as ttcp.
-u, --udp $IPERF_UDP Use UDP rather than TCP. See also the -b option.
-w, --window #[KM] $TCP_WINDOW_SIZE Sets the socket buffer sizes to the specified value. For TCP, this sets the TCP window size. For UDP it is just the buffer which datagrams are received in, and so limits the largest receivable datagram size.
-B, --bind host $IPERF_BIND Bind to host, one of this machine's addresses. For the client this sets the outbound interface. For a server this sets the incoming interface. This is only useful on multihomed hosts, which have multiple network interfaces. 

For Iperf in UDP server mode, this is also used to bind and join to a multicast group. Use addresses in the range 224.0.0.0 to 239.255.255.255 for multicast. See also the -T option.

-C, --compatibility $IPERF_COMPAT Compatibility mode allows for use with older version of iperf. This mode is not required for interoperability but it is highly recommended. In some cases when using representative streaming you could cause a 1.7 server to crash or cause undesired connection attempts.

-M, --mss #[KM} $IPERF_MSS Attempt to set the TCP maximum segment size (MSS) via the TCP_MAXSEG option. The MSS is usually the MTU - 40 bytes for the TCP/IP header. For ethernet, the MSS is 1460 bytes (1500 byte MTU). This option is not implemented on many OSes.
-N, --nodelay $IPERF_NODELAY Set the TCP no delay option, disabling Nagle's algorithm. Normally this is only disabled for interactive applications like telnet.
-V (from v1.6 or higher) . Bind to an IPv6 address
Server side:
$ iperf -s -V 

Client side:
$ iperf -c <Server IPv6 Address> -V
 

Note: On version 1.6.3 and later a specific IPv6 Address does not need to be bound with the -B option, previous 1.6 versions do. Also on most OSes using this option will also respond to IPv4 clients using IPv4 mapped addresses.
Server specific options
-s, --server $IPERF_SERVER Run Iperf in server mode.
-D (from v1.2 or higher) . Run the server as a daemon (Unix platforms)
On Win32 platforms where services are available, Iperf will start running as a service.
-R (only for Windows, from v1.2 or higher) . Remove the Iperf service (if it's running). 
-o (only for Windows, from v1.2 or higher) . Redirect output to given file. 
-c, --client host $IPERF_CLIENT If Iperf is in server mode, then specifying a host with -c will limit the connections that Iperf will accept to the host specified. Does not work well for UDP.
-P, --parallel # $IPERF_PARALLEL The number of connections to handle by the server before closing. Default is 0 (which means to accept connections forever).
Client specific options
-b, --bandwidth #[KM] $IPERF_BANDWIDTH The UDP bandwidth to send at, in bits/sec. This implies the -u option. Default is 1 Mbit/sec.
-c, --client host $IPERF_CLIENT Run Iperf in client mode, connecting to an Iperf server running on host.
-d, --dualtest $IPERF_DUALTEST Run Iperf in dual testing mode. This will cause the server to connect back to the client on the port specified in the -L option (or defaults to the port the client connected to the server on). This is done immediately therefore running the tests simultaneously. If you want an alternating test try -r.
-n, --num #[KM] $IPERF_NUM The number of buffers to transmit. Normally, Iperf sends for 10 seconds. The -n option overrides this and sends an array of len bytes num times, no matter how long that takes. See also the -l and -t options.
-r, --tradeoff $IPERF_TRADEOFF Run Iperf in tradeoff testing mode. This will cause the server to connect back to the client on the port specified in the -L option (or defaults to the port the client connected to the server on). This is done following the client connection termination, therefore running the tests alternating. If you want an simultaneous test try -d.
-t, --time # $IPERF_TIME The time in seconds to transmit for. Iperf normally works by repeatedly sending an array of len bytes for time seconds. Default is 10 seconds. See also the -l and -n options.
-L, --listenport # $IPERF_LISTENPORT This specifies the port that the server will connect back to the client on. It defaults to the port used to connect to the server from the client.
-P, --parallel # $IPERF_PARALLEL The number of simultaneous connections to make to the server. Default is 1. Requires thread support on both the client and server.
-S, --tos # $IPERF_TOS The type-of-service for outgoing packets. (Many routers ignore the TOS field.) You may specify the value in hex with a '0x' prefix, in octal with a '0' prefix, or in decimal. For example, '0x10' hex = '020' octal = '16' decimal. The TOS numbers specified in RFC 1349 are:  
    IPTOS_LOWDELAY     minimize delay        0x10
    IPTOS_THROUGHPUT   maximize throughput   0x08
    IPTOS_RELIABILITY  maximize reliability  0x04
    IPTOS_LOWCOST      minimize cost         0x02
    
-T, --ttl # $IPERF_TTL The time-to-live for outgoing multicast packets. This is essentially the number of router hops to go through, and is also used for scoping. Default is 1, link-local.
-F (from v1.2 or higher) . Use a representative stream to measure bandwidth, e.g. :- 
$ iperf -c <server address> -F <file-name>
-I (from v1.2 or higher) . Same as -F, input from stdin.
Miscellaneous options
-h, --help   Print out a summary of commands and quit.
-v, --version   Print version information and quit. Prints 'pthreads' if compiled with POSIX threads, 'win32 threads' if compiled with Microsoft Win32 threads, or 'single threaded' if compiled without threads.

Tuning a TCP connection

The primary goal of Iperf is to help in tuning TCP connections over a particular path. The most fundamental tuning issue for TCP is the TCP window size, which controls how much data can be in the network at any one point. If it is too small, the sender will be idle at times and get poor performance. The theoretical value to use for the TCP window size is the bandwidth delay product,
bottleneck bandwidth * round trip time
In the below modi4/cyclops example, the bottleneck link is a 45 Mbit/sec DS3 link and the round trip time measured with ping is 42 ms. The bandwidth delay product is
45 Mbit/sec * 42 ms
= (45e6) * (42e-3)
= 1890000 bits
= 230 KByte
That is a starting point for figuring the best window size; setting it higher or lower may produce better results. In our example, buffer sizes over 130K did not improve the performance, despite the bandwidth delay product of 230K.

Note that many OSes and hosts have upper limits on the TCP window size. These may be as low as 64 KB, or as high as several MB. Iperf tries to detect when these occur and give a warning that the actual and requested window sizes are not equal (as below, though that is due to rounding in IRIX). PSC has a list detailing how to change the default and maximum window sizes for various OSes. For more information on TCP window sizes, see the User's Guide to TCP Windows.

Here is an example session, between node1 in Illinois and node2 in North Carolina. These are connected via the vBNS backbone and a 45 Mbit/sec DS3 link. Notice we improve bandwidth performance by a factor of 3 using proper TCP window sizes. Use the adaptive window sizes feature on platforms which allow setting window sizes in the granularity of bytes.

Another test to do is run parallel TCP streams. If the total aggregate bandwidth is more than what an individual stream gets, something is wrong. Either the TCP window size is too small, or the OS's TCP implementation has bugs, or the network itself has deficiencies. See above for TCP window sizes; otherwise diagnosing which is somewhat difficult. If Iperf is compiled with pthreads, a single client and server can test this, otherwise setup multiple clients and servers on different ports. Here's an example where a single stream gets 16.5 Mbit/sec, but two parallel streams together get 16.7 + 9.4 = 26.1 Mbit/sec, even when using large TCP window sizes: 
node2> iperf -s -w 300k

A secondary tuning issue for TCP is the maximum transmission unit (MTU). To be most effective, both hosts should support Path MTU Discovery. PSC has a list detailing what OSes support Path MTU Discovery. Hosts without Path MTU Discovery often use 536 as the MSS, which wastes bandwidth and processing time. Use the -m option to display what MSS is being used, and see if this matches what you expect. Often it is around 1460 bytes for ethernet.

Iperf supports other tuning options, which were added for exceptional network situations like HIPPI-to-HIPPI over ATM.

Tuning a UDP connection

Iperf creates a constant bit rate UDP stream. This is a very artificial stream, similar to voice communication but not much else.

You will want to adjust the datagram size (-l) to the size your application uses.

The server detects UDP datagram loss by ID numbers in the datagrams. Usually a UDP datagram becomes several IP packets. Losing a single IP packet will lose the entire datagram. To measure packet loss instead of datagram loss, make the datagrams small enough to fit into a single packet, using the -l option. The default size of 1470 bytes works for ethernet. Out-of-order packets are also detected. (Out-of-order packets cause some ambiguity in the lost packet count; Iperf assumes they are not duplicate packets, so they are excluded from the lost packet count.) Since TCP does not report loss to the user, I find UDP tests helpful to see packet loss along a path.

Jitter calculations are continuously computed by the server, as specified by RTP in RFC 1889. The client records a 64 bit second/microsecond timestamp in the packet. The server computes the relative transit time as (server's receive time - client's send time). The client's and server's clocks do not need to be synchronized; any difference is subtracted out in the jitter calculation. Jitter is the smoothed mean of differences between consecutive transit times.

Notice the higher jitter due to datagram reassembly when using larger 32 KB datagrams, each split into 23 packets of 1500 bytes. The higher datagram loss seen here may be due to the burstiness of the traffic, which is 23 back-to-back packets and then a long pause, rather than evenly spaced individual packets.

Multicast 

To test multicast, run several servers with the bind option (-B, --bind) set 
to the multicast group address. Run the client, connecting to the multicast 
group address and setting the TTL (-T, --ttl) as needed. Unlike normal TCP and 
UDP tests, multicast servers may be started after the client. In that case, 
datagrams sent before the server started show up as losses in the first periodic 
report (61 datagrams on arno below).

IPv6 Mode 
  
Download the IPv6 version of this release.
Get the IPv6 address of the node using the 'ifconfig' command.
Use the -V option to indicate that you are using an IPv6 address Please note that we need to explicitly bind the server address also. 
  
Server side:
 $ iperf -s -V
  
Client side:
$ iperf -c <Server IPv6 Address> -V 
  
Note: Iperf version 1.6.2 and eariler require a IPv6 address to be explicitly bound
  with the -B option for the server.







  
Using Representative Streams to measure 
  bandwidth 
  
Use the -F or -I option. If you want to test how your network performs 
  with compressed / uncompressed streams, just create representative streams and 
  use the -F option to test it. This is usually due to the link layer 
  compressing data. 
  
The -F option is for file input.
The -I option is for input from stdin. 
  
E.g. 
Client: $  iperf -c <server address> -F <file-name>

          
Client: $  iperf -c <server address> -I 







  
Running the server as a daemon 
  
Use the -D command line option to run the server as a daemon. Redirect the 
  output to a file.
E.g. iperf -s -D > 
  iperfLog. This will have the Iperf Server running 
  as a daemon and the server messages will be logged in the file iperfLog. 








  
Using Iperf as a Service under Win32 
  
There are three options for Win32: 
  

  

    
-o outputfilename 
    
output the messages into the specified file 
    
-s -D 
    
install Iperf as a service and run it 
    
-s -R 
    
uninstall the Iperf service 

  
Examples: 
  

    
iperf -s -D -o iperflog.txt 
    
will install the Iperf service and run it. Messages will be reported 
    into "%windir%\system32\iperflog.txt" 
    

    
iperf -s -R 
    
will uninstall the Iperf service if it is installed. 
    
Note: If you stop want to restart the Iperf service after having killed 
    it with the Microsoft Management Console or the Windows Task Manager, make 
    sure to use the proper OPTION in the service properties dialog.

 *
 * E.g. Use a gzipped file to measure the transfer rates for 
 * compressed data
 * Use an MPEG file to measure the transfer rates of 
 * Multimedia data formats
 * Use a plain BMP file to measure the transfer rates of 
 * Uncompressed data
 *
 * This is beneficial especially in measuring bandwidth across WAN
 * links where data compression takes place before data transmission

   The LONG_OPTIONS argument to gnu_getopt_long or getopt_long_only is a vector
   of `struct option' terminated by an element containing a name which is
   zero.

   The field `has_arg' is:
   no_argument		(or 0) if the option does not take an argument,
   required_argument	(or 1) if the option requires an argument,
   optional_argument 	(or 2) if the option takes an optional argument.

   If the field `flag' is not NULL, it points to a variable that is set
   to the value given in the field `val' when the option is found, but
   left unchanged if the option is not found.

   To have a long-named option do something other than set an `int' to
   a compiled-in constant, such as set a value from `gnu_optarg', set the
   option's `flag' field to zero and its `val' field to a nonzero
   value (the equivalent single-letter option character, if there is
   one).  For long options that have a zero `flag' field, `gnu_getopt'
   returns the contents of the `val' field.  */

//
//  MODULE: service.h
//
//  AUTHOR: Craig Link
//
//
//  Comments:  The use of this header file and the accompanying service.c
//  file simplifies the process of writting a service.  You as a developer
//  simply need to follow the TODO's outlined in this header file, and 
//  implement the ServiceStart() and ServiceStop() functions.
//  
//  There is no need to modify the code in service.c.  Just add service.c
//  to your project and link with the following libraries...
//
//  libcmt.lib kernel32.lib advapi.lib shell32.lib
//
//  This code also supports unicode.  Be sure to compile both service.c and
//  and code #include "service.h" with the same Unicode setting.
//
//  Upon completion, your code will have the following command line interface
//
//   -?                to display this list
//   -install          to install the service
//   -remove           to remove the service
//   -debug    to run as a console app for debugging
//
//  Note: This code also implements Ctrl+C and Ctrl+Break handlers
//        when using the debug option.  These console events cause
//        your ServiceStop routine to be called
//
//        Also, this code only handles the OWN_SERVICE service type
//        running in the LOCAL_SYSTEM security context.
//
//        To control your service ( start, stop, etc ) you may use the
//        Services control panel applet or the NET.EXE program.
//
//        To aid in writing/debugging service, the
//        SDK contains a utility (MSTOOLS\BIN\SC.EXE) that
//        can be used to control, configure, or obtain service status.
//        SC displays complete status for any service/driver
//        in the service database, and allows any of the configuration
//        parameters to be easily changed at the command line.
//        For more information on SC.EXE, type SC at the command line.
//

/*
 * modified Mar.07, 2002 by Feng Qin 
 *          Mar.15, 2002
 *
 * removed some functions we don't use at all
 * add code to start the service immediately after service is installed

dnl
dnl the "ISO C9X: 7.18 Integer types " section requires the
dnl existence of an include file  that defines a set of
dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older
dnl installations will not provide this file, but some will have the
dnl very same definitions in . In other enviroments we can
dnl use the inet-types in  which would define the typedefs
dnl int8_t and u_int8_t respectivly.
dnl
dnl This macros will create a local "_stdint.h" or the headerfile given
dnl as an argument. In many cases that file will just "#include
dnl " or "#include ", while in other environments
dnl it will provide the set of basic 'stdint's definitions/typedefs:
dnl
dnl   int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
dnl   int_least32_t.. int_fast32_t.. intmax_t
dnl
dnl which may or may not rely on the definitions of other files, or
dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
dnl type.
dnl
dnl if your header files require the stdint-types you will want to
dnl create an installable file mylib-int.h that all your other
dnl installable header may include. So if you have a library package
dnl named "mylib", just use
dnl
dnl      AX_CREATE_STDINT_H(mylib-int.h)
dnl
dnl in configure.ac and go to install that very header file in
dnl Makefile.am along with the other headers (mylib.h) - and the
dnl mylib-specific headers can simply use "#include " to
dnl obtain the stdint-types.
dnl
dnl Remember, if the system already had a valid , the
dnl generated file will include it directly. No need for fuzzy
dnl HAVE_STDINT_H things...

.SH DESCRIPTION
iperf is a tool for performing network throughput measurements.  It can test
either TCP or UDP throughput.  To perform an iperf test the user must
establish both a server (to discard traffic) and a client (to generate
traffic).  
.SH "GENERAL OPTIONS"
.TP
.BR -f ", " --format " "
[kmKM]   format to report: Kbits, Mbits, KBytes, MBytes
.TP
.BR -h ", " --help " "
print a help synopsis
.TP
.BR -i ", " --interval " \fIn\fR"
pause \fIn\fR seconds between periodic bandwidth reports
.TP
.BR -l ", " --len " \fIn\fR[KM]"
set length read/write buffer to \fIn\fR (default 8 KB)
.TP
.BR -m ", " --print_mss " "
print TCP maximum segment size (MTU - TCP/IP header)
.TP
.BR -o ", " --output " "
output the report or error message to this specified file
.TP
.BR -p ", " --port " \fIn\fR"
set server port to listen on/connect to to \fIn\fR (default 5001)
.TP
.BR -u ", " --udp " "
use UDP rather than TCP
.TP
.BR -w ", " --window " \fIn\fR[KM]"
TCP window size (socket buffer size)
.TP
.BR -B ", " --bind " "
bind to , an interface or multicast address
.TP
.BR -C ", " --compatibility " "
for use with older versions does not sent extra msgs
.TP
.BR -M ", " --mss " \fIn\fR"
set TCP maximum segment size (MTU - 40 bytes)
.TP
.BR -N ", " --nodelay " "
set TCP no delay, disabling Nagle's Algorithm
.TP
.BR -v ", " --version " "
print version information and quit
.TP
.BR -V ", " --IPv6Version " "
Set the domain to IPv6
.TP
.BR -x ", " --reportexclude " "
[CDMSV]   exclude C(connection) D(data) M(multicast) S(settings) V(server) reports
.TP
.BR -y ", " --reportstyle " C|c"
if set to C or c report results as CSV (comma separated values)
.SH "SERVER SPECIFIC OPTIONS"
.TP
.BR -s ", " --server " "
run in server mode
.TP
.BR -U ", " --single_udp " "
run in single threaded UDP mode
.TP
.BR -D ", " --daemon " "
run the server as a daemon
.SH "CLIENT SPECIFIC OPTIONS"
.TP
.BR -b ", " --bandwidth " \fIn\fR[KM]"
set target bandwidth to \fIn\fR bits/sec (default 1 Mbit/sec).
This setting requires UDP (-u).
.TP
.BR -c ", " --client " "
run in client mode, connecting to 
.TP
.BR -d ", " --dualtest " "
Do a bidirectional test simultaneously
.TP
.BR -n ", " --num " \fIn\fR[KM]"
number of bytes to transmit (instead of -t)
.TP
.BR -r ", " --tradeoff " "
Do a bidirectional test individually
.TP
.BR -t ", " --time " \fIn\fR"
time in seconds to transmit for (default 10 secs)
.TP
.BR -F ", " --fileinput " "
input the data to be transmitted from a file
.TP
.BR -I ", " --stdin " "
input the data to be transmitted from stdin
.TP
.BR -L ", " --listenport " \fIn\fR"
port to recieve bidirectional tests back on
.TP
.BR -P ", " --parallel " \fIn\fR"

   REQUIRE_ORDER means don't recognize them as options;
   stop option processing when the first non-option is seen.
   This is what Unix does.
   This mode of operation is selected by either setting the environment
   variable POSIXLY_CORRECT, or using `+' as the first character
   of the list of option characters.

   PERMUTE is the default.  We permute the contents of ARGV as we scan,
   so that eventually all the non-options are at the end.  This allows options
   to be given in any order, even with programs that were not written to
   expect this.

   RETURN_IN_ORDER is an option available to programs that were written
   to expect options and other ARGV-elements in any order and that care about
   the ordering of the two.  We describe each non-option ARGV-element
   as if it were the argument of an option with character code 1.
   Using `-' as the first character of the list of option characters
   selects this mode of operation.

   The special argument `--' forces an end of option-scanning regardless
   of the value of `ordering'.  In the case of RETURN_IN_ORDER, only

/* Scan elements of ARGV (whose length is ARGC) for option characters
   given in OPTSTRING.

   If an element of ARGV starts with '-', and is not exactly "-" or "--",
   then it is an option element.  The characters of this element
   (aside from the initial '-') are option characters.  If `gnu_getopt'
   is called repeatedly, it returns successively each of the option characters
   from each of the option elements.

   If `gnu_getopt' finds another option character, it returns that character,
   updating `gnu_optind' and `nextchar' so that the next call to `gnu_getopt' can
   resume the scan with the following option character or ARGV-element.

   If there are no more option characters, `gnu_getopt' returns -1.
   Then `gnu_optind' is the index in ARGV of the first ARGV-element
   that is not an option.  (The ARGV-elements have been permuted
   so that those that are not options now come last.)

   OPTSTRING is a string containing the legitimate option characters.
   If an option character is seen that is not listed in OPTSTRING,
   return '?' after printing an error message.  If you set `gnu_opterr' to
   zero, the error message is suppressed but we still return '?'.

   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
   so the following text in the same ARGV-element, or the text of the following
   ARGV-element, is returned in `gnu_optarg'.  Two colons mean an option that
   wants an optional arg; if there is text in the current ARGV-element,
   it is returned in `gnu_optarg', otherwise `gnu_optarg' is set to zero.

   If OPTSTRING starts with `-' or `+', it requests different methods of
   handling the non-option ARGV-elements.
   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.

   Long-named options begin with `--' instead of `-'.
   Their names may be abbreviated as long as the abbreviation is unique
   or is an exact match for some defined option.  If they have an
   argument, it follows the option name in the same ARGV-element, separated
   from the option name by a `=', or else the in next ARGV-element.
   When `gnu_getopt' finds a long-named option, it returns 0 if that option's
   `flag' field is nonzero, the value of the option's `val' field
   if the `flag' field is zero.

   The elements of ARGV aren't really const, because we permute them.
   But we pretend they're const in the prototype to be compatible
   with other systems.

   LONGOPTS is a vector of `struct option' terminated by an
   element containing a name which is zero.

   LONGIND returns the index in LONGOPT of the long-named option found.
   It is only valid when a long-named option has been found by the most
   recent call.

   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
   long-named options.  */
