SMOKE-16 packages are available from: + + http://geocities.com/bsittler/#smoke16 + +OVERVIEW OF THE ARGUMENT PARSER +=============================== + +The getopt(), getopt_long() and getopt_long_only() functions parse +command line arguments. The argc and argv parameters passed to these +functions correspond to the argument count and argument list passed to +your program's main() function at program start-up. Element 0 of the +argument list conventionally contains the name of your program. Any +remaining arguments starting with "-" (except for "-" or "--" by +themselves) are option arguments, some of include option values. This +family of getopt() functions allows intermixed option and non-option +arguments anywhere in the argument list, except that "--" by itself +causes the remaining elements of the argument list to be treated as +non-option arguments. + +[ See the parts of this document labeled "DOCUMENTATION" and + "WHY RE-INVENT THE WHEEL?" for a more information. ] + +FILES +===== + +The following four files constitute the my_getopt package: + + LICENSE - license and warranty information for my_getopt + my_getopt.c - implementation of my getopt replacement + my_getopt.h - interface for my getopt replacement + getopt.h - a header file to make my getopt look like GNU getopt + +USAGE +===== + +To use my_getopt in your application, include the following line to +your main program source: + + #include "getopt.h" + +This line should appear after your standard system header files to +avoid conflicting with your system's built-in getopt. + +Then compile my_getopt.c into my_getopt.o, and link my_getopt.o into +your application: + + $ cc -c my_getopt.c + $ ld -o app app.o ... my_getopt.o + +To avoid conflicting with standard library functions, the function +names and global variables used by my_getopt all begin with `my_'. To +ensure compatibility with existing C programs, the `getopt.h' header +file uses the C preprocessor to redefine names like getopt, optarg, +optind, and so forth to my_getopt, my_optarg, my_optind, etc. + +SAMPLE PROGRAM +============== + +There is also a public-domain sample program: + + main.c - main() for a sample program using my_getopt + Makefile - build script for the sample program (called `copy') + +To build and test the sample program: + + $ make + $ ./copy -help + $ ./copy -version + +The sample program bears a slight resemblance to the UNIX `cat' +utility, but can be used rot13-encode streams, and can redirect output +to a file. + +DOCUMENTATION +============= + +There is not yet any real documentation for my_getopt. For the moment, +use the Linux manual page for getopt. It has its own copyright and +license; view the file `getopt.3' in a text editor for more details. + + getopt.3 - the manual page for GNU getopt + getopt.txt - preformatted copy of the manual page for GNU getopt, + for your convenience + +WHY RE-INVENT THE WHEEL? +======================== + +I re-implemented getopt, getopt_long, and getopt_long_only because +there were noticable bugs in several versions of the GNU +implementations, and because the GNU versions aren't always available +on some systems (*BSD, for example.) Other systems don't include any +sort of standard argument parser (Win32 with Microsoft tools, for +example, has no getopt.) + +These should do all the expected Unix- and GNU-style argument +parsing, including permution, bunching, long options with single or +double dashes (double dashes are required if you use +my_getopt_long,) and optional arguments for both long and short +options. A word with double dashes all by themselves halts argument +parsing. A required long option argument can be in the same word as +the option name, separated by '=', or in the next word. An optional +long option argument must be in the same word as the option name, +separated by '='. + +As with the GNU versions, a '+' prefix to the short option +specification (or the POSIXLY_CORRECT environment variable) disables +permution, a '-' prefix to the short option specification returns 1 +for non-options, ':' after a short option indicates a required +argument, and '::' after a short option specification indicates an +optional argument (which must appear in the same word.) If you'd like +to recieve ':' instead of '?' for missing option arguments, prefix the +short option specification with ':'. + +The original intent was to re-implement the documented behavior of +the GNU versions, but I have found it necessary to emulate some of +the undocumented behavior as well. Some programs depend on it. + +KNOWN BUGS +========== + +The GNU versions support POSIX-style -W "name=value" long +options. Currently, my_getopt does not support these, because I +don't have any documentation on them (other than the fact that they +are enabled by "W;" in the short option specification.) As a +temporary workaround, my_getopt treats "W;" in the short option +string identically to "W:". + +The GNU versions support internationalized/localized +messages. Currently, my_getopt does not. + +There should be re-entrant versions of all these functions so that +multiple threads can parse arguments simultaneously. diff --git a/common/win/my_getopt-1.5/getopt.3 b/common/win/my_getopt-1.5/getopt.3 new file mode 100644 index 00000000..a63fcd82 --- /dev/null +++ b/common/win/my_getopt-1.5/getopt.3 @@ -0,0 +1,288 @@ +.\" (c) 1993 by Thomas Koenig (ig25@rz.uni-karlsruhe.de) +.\" +.\" Permission is granted to make and distribute verbatim copies of this +.\" manual provided the copyright notice and this permission notice are +.\" preserved on all copies. +.\" +.\" Permission is granted to copy and distribute modified versions of this +.\" manual under the conditions for verbatim copying, provided that the +.\" entire resulting derived work is distributed under the terms of a +.\" permission notice identical to this one +.\" +.\" Since the Linux kernel and libraries are constantly changing, this +.\" manual page may be incorrect or out-of-date.

Its arguments +.I argc +and +.I argv +are the argument count and array as passed to the +.B main() +function on program invocation. +An element of \fIargv\fP that starts with `-' (and is not exactly "-" or "--") +is an option element. The characters of this element +(aside from the initial `-') are option characters. If \fBgetopt()\fP +is called repeatedly, it returns successively each of the option characters +from each of the option elements. +.PP +If \fBgetopt()\fP finds another option character, it returns that +character, updating the external variable \fIoptind\fP and a static +variable \fInextchar\fP so that the next call to \fBgetopt()\fP can +resume the scan with the following option character or +\fIargv\fP-element. +.PP +If there are no more option characters, \fBgetopt()\fP returns +\fBEOF\fP. Then \fIoptind\fP is the index in \fIargv\fP of the first +\fIargv\fP-element that is not an option. +.PP +.I optstring +is a string containing the legitimate option characters. If such a +character is followed by a colon, the option requires an argument, so +\fBgetopt\fP places a pointer to the following text in the same +\fIargv\fP-element, or the text of the following \fIargv\fP-element, in +.IR optarg . +Two colons mean an option takes +an optional arg; if there is text in the current \fIargv\fP-element, +it is returned in \fIoptarg\fP, otherwise \fIoptarg\fP is set to zero. +.PP +By default, \fBgetargs()\fP permutes the contents of \fIargv\fP as it +scans, so that eventually all the non-options are at the end. Two +other modes are also implemented. If the first character of +\fIoptstring\fP is `+' or the environment variable POSIXLY_CORRECT is +set, then option processing stops as soon as a non-option argument is +encountered. If the first character of \fIoptstring\fP is `-', then +each non-option \fIargv\fP-element is handled as if it were the argument of +an option with character code 1. (This is used by programs that were +written to expect options and other \fIargv\fP-elements in any order +and that care about the ordering of the two.) +The special argument `--' forces an end of option-scanning regardless +of the scanning mode. +.PP +If \fBgetopt()\fP does not recognize an option character, it prints an +error message to stderr, stores the character in \fIoptopt\fP, and +returns `?'. The calling program may prevent the error message by +setting \fIopterr\fP to 0. +.PP +The +.B getopt_long() +function works like +.B getopt() +except that it also accepts long options, started out by two dashes. +Long option names may be abbreviated if the abbreviation is +unique or is an exact match for some defined option. A long option +may take a parameter, of the form +.B --arg=param +or +.BR "--arg param" . +.PP +.I longopts +is a pointer to the first element of an array of +.B struct option +declared in +.B <getopt.h> +as +.nf +.sp +.in 10 +struct option { +.in 14 +const char *name; +int has_arg; +int *flag; +int val; +.in 10 +}; +.fi +.PP +The meanings of the different fields are: +.TP +.I name +is the name of the long option. +.TP +.I has_arg +is: +\fBno_argument\fP (or 0) if the option does not take an argument, +\fBrequired_argument\fP (or 1) if the option requires an argument, or +\fBoptional_argument\fP (or 2) if the option takes an optional argument. +.TP +.I flag +specifies how results are returned for a long option. If \fIflag\fP +is \fBNULL\fP, then \fBgetopt_long()\fP returns \fIval\fP. (For +example, the calling program may set \fIval\fP to the equivalent short +option character.) Otherwise, \fBgetopt_long()\fP returns 0, and +\fIflag\fP points to a variable which is set to \fIval\fP if the +option is found, but left unchanged if the option is not found. +.TP +\fIval\fP +is the value to return, or to load into the variable pointed +to by \fIflag\fP. +.PP +The last element of the array has to be filled with zeroes. +.PP +If \fIlongindex\fP is not \fBNULL\fP, it +points to a variable which is set to the index of the long option relative to +.IR longopts . +.PP +\fBgetopt_long_only()\fP is like \fBgetopt_long()\fP, but `-' as well +as `--' can indicate a long option. If an option that starts with `-' +(not `--') doesn't match a long option, but does match a short option, +it is parsed as a short option instead. +.SH "RETURN VALUE" +The +.B getopt() +function returns the option character if the option was found +successfully, `:' if there was a missing parameter for one of the +options, `?' for an unknown option character, or \fBEOF\fP +for the end of the option list. +.PP +\fBgetopt_long()\fP and \fBgetopt_long_only()\fP also return the option +character when a short option is recognized. For a long option, they +return \fIval\fP if \fIflag\fP is \fBNULL\fP, and 0 otherwise. Error +and EOF returns are the same as for \fBgetopt()\fP, plus `?' for an +ambiguous match or an extraneous parameter. +.SH "ENVIRONMENT VARIABLES" +.TP +.SM +.B POSIXLY_CORRECT +If this is set, then option processing stops as soon as a non-option +argument is encountered. +.SH "EXAMPLE" +The following example program, from the source code, illustrates the +use of +.BR getopt_long() +with most of its features. +.nf +.sp +#include <stdio.h> + +int +main (argc, argv) + int argc; + char **argv; +{ + int c; + int digit_optind = 0; + + while (1) + { + int this_option_optind = optind ? optind : 1; + int option_index = 0; + static struct option long_options[] = + { + {"add", 1, 0, 0}, + {"append", 0, 0, 0}, + {"delete", 1, 0, 0}, + {"verbose", 0, 0, 0}, + {"create", 1, 0, 'c'}, + {"file", 1, 0, 0}, + {0, 0, 0, 0} + }; + + c = getopt_long (argc, argv, "abc:d:012", + long_options, &option_index); + if (c == -1) + break; + + switch (c) + { + case 0: + printf ("option %s", long_options[option_index].name); + if (optarg) + printf (" with arg %s", optarg); + printf ("\\n"); + break; + + case '0': + case '1': + case '2': + if (digit_optind != 0 && digit_optind != this_option_optind) + printf ("digits occur in two different argv-elements.\\n"); + digit_optind = this_option_optind; + printf ("option %c\\n", c); + break; + + case 'a': + printf ("option a\\n"); + break; + + case 'b': + printf ("option b\\n"); + break; + + case 'c': + printf ("option c with value `%s'\\n", optarg); + break; + + case 'd': + printf ("option d with value `%s'\\n", optarg); + break; + + case '?': + break; + + default: + printf ("?? getopt returned character code 0%o ??\\n", c); + } + } + + if (optind < argc) + { + printf ("non-option ARGV-elements: "); + while (optind < argc) + printf ("%s ", argv[optind++]); + printf ("\\n"); + } + + exit (0); +} +.fi +.SH "BUGS" +This manpage is confusing. +.SH "CONFORMING TO" +.TP +\fBgetopt()\fP: +POSIX.1, provided the environment variable POSIXLY_CORRECT is set. +Otherwise, the elements of \fIargv\fP aren't really const, because we +permute them.

Error and EOF returns are the same as for getopt(), + plus `?' for an ambiguous match or an extraneous parame- + ter. + +ENVIRONMENT VARIABLES + POSIXLY_CORRECT + If this is set, then option processing stops as + soon as a non-option argument is encountered. + +EXAMPLE + The following example program, from the source code, + illustrates the use of getopt_long() with most of its fea- + tures. + + #include <stdio.h> + + int + main (argc, argv) + int argc; + char **argv; + { + int c; + int digit_optind = 0; + + while (1) + { + int this_option_optind = optind ? optind : 1; + int option_index = 0; + static struct option long_options[] = + { + {"add", 1, 0, 0}, + + + +GNU Aug 30, 1995 3 + + + + + +GETOPT(3) Linux Programmer's Manual GETOPT(3) + + + {"append", 0, 0, 0}, + {"delete", 1, 0, 0}, + {"verbose", 0, 0, 0}, + {"create", 1, 0, 'c'}, + {"file", 1, 0, 0}, + {0, 0, 0, 0} + }; + + c = getopt_long (argc, argv, "abc:d:012", + long_options, &option_index); + if (c == -1) + break; + + switch (c) + { + case 0: + printf ("option %s", long_options[option_index].name); + if (optarg) + printf (" with arg %s", optarg); + printf ("\n"); + break; + + case '0': + case '1': + case '2': + if (digit_optind != 0 && digit_optind != this_option_optind) + printf ("digits occur in two different argv-elements.\n"); + digit_optind = this_option_optind; + printf ("option %c\n", c); + break; + + case 'a': + printf ("option a\n"); + break; + + case 'b': + printf ("option b\n"); + break; + + case 'c': + printf ("option c with value `%s'\n", optarg); + break; + + case 'd': + printf ("option d with value `%s'\n", optarg); + break; + + case '?': + break; + + default: + printf ("?? getopt returned character code 0%o ??\n", c); + } + } + + + +GNU Aug 30, 1995 4 + + + + + +GETOPT(3) Linux Programmer's Manual GETOPT(3) + + + if (optind < argc) + { + printf ("non-option ARGV-elements: "); + while (optind < argc) + printf ("%s ", argv[optind++]); + printf ("\n"); + } + + exit (0); + } + +BUGS + This manpage is confusing. + +CONFORMING TO + getopt(): + POSIX.1, provided the environment variable + POSIXLY_CORRECT is set.
