NAME

       msgids - discover all message queue identifiers

SYNOPSIS

       #include <sys/msg.h>

       int msgids(int *buf, uint_t nids, uint_t  *pnids);

DESCRIPTION

       The  msgids()  function copies all active message queue identifiers from the system into the user-defined buffer specified by buf, provided
       that the number of such identifiers is not greater than the number of integers the buffer can contain, as specified by nids.  If  the  size
       of the buffer is insufficient to contain all of the active message queue identifiers in the system, none are copied.

       Whether or not the size of the buffer is sufficient to contain all of them, the number of active message queue identifiers in the system is
       copied into the unsigned integer pointed to by pnids.

       If nids is 0 or less than the number of active message queue identifiers in the system, buf is ignored.

RETURN VALUES

       Upon successful completion, msgids() returns 0.	Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The msgids() function will fail if:

       EFAULT	 The buf or pnids argument points to an illegal address.

USAGE

       The msgids() function returns a snapshot of all the active message queue identifiers in the system.  More may be  added	and  some  may	be
       removed before they can be used by the caller.

EXAMPLES

       Example 1 msgids() example

       This is sample C code indicating how to use the msgids() function (see msgsnap(2)):

	 void
	 examine_queues()
	 {
	      int *ids = NULL;
	      uint_t nids = 0;
	      uint_t n;
	      int i;

	      for (;;) {
		   if (msgids(ids, nids, &n) != 0) {
			perror("msgids");
			exit(1);
		   }
		   if (n <= nids)     /* we got them all */
			break;
		   /* we need a bigger buffer */
		   ids = realloc(ids, (nids = n) * sizeof (int));
	      }

	      for (i = 0; i < n; i++)
		   process_msgid(ids[i]);

	      free(ids);
	 }

NAME

       xgettext - extract gettext call strings from C programs

SYNOPSIS

       xgettext [-ns] [-a [-x exclude-file]] [-c comment-tag]
	    [-d default-domain] [-j] [-m prefix] [-M suffix]
	    [-p pathname] -| filename...

       xgettext -h

DESCRIPTION

       The  xgettext  utility is used to automate the creation of portable message files (.po). A .po file contains copies of "C" strings that are
       found in  ANSI C source code in filename or the standard input if  `-' is specified on the command line. The  .po file can be used as input
       to the  msgfmt(1) utility, which produces a binary form of the message file that can be	used by application during run-time.

       xgettext  writes msgid strings from gettext(3C) calls in  filename to the default output file messages.po. The default output file name can
       be changed by  -d option. msgid strings in dgettext() calls are written to the output file domainname.po  where	domainname  is	the  first
       parameter to the dgettext() call.

       By  default,  xgettext  creates	a   .po  file  in  the current working directory, and each entry is in the same order that the strings are
       extracted from filenames. When the -p option is specified, the  .po file is created in the  pathname directory. An  existing  .po  file	is
       overwritten.

       Duplicate   msgids are written to the  .po file as comment lines. When the  -s option is specified, the	.po is sorted by the msgid string,
       and all duplicated msgids are removed. All  msgstr directives in the .po file are empty unless the -m option is used.

OPTIONS

       The following options are supported:

       -n		    Add comment lines to the output file indicating file name and line number in the  source  file  where  each  extracted
			    string is encountered. These lines appear before each msgid in the following format:

			      # # File: filename, line: line-number

       -s		    Generate output sorted by  msgids with all duplicate  msgids removed.

       -a		    Extract all strings, not just those found in gettext(3C), and dgettext() () calls. Only one  .po file is created.

       -c comment-tag	    The  comment  block beginning with comment-tag as the first token of the comment block is added to the output .po file
			    as	# delimited comments. For multiple domains, xgettext directs comments and messages to the prevailing text domain.

       -d default-domain    Rename default output file from messages.po to default-domain .po.

       -j		    Join messages with existing message files.	If a .po file does not exist, it is created.  If a .po	file  does  exist,
			    new  messages  are	appended.  Any duplicate msgids are commented out in the resulting .po file.  Domain directives in
			    the existing .po file are ignored. Results not guaranteed if the existing message file has been edited.

       -m prefix	    Fill in the msgstr with  prefix. This is useful for debugging purposes. To make msgstr  identical  to  msgid,  use	an
			    empty string  ("") for prefix.

       -M suffix	    Fill in the msgstr with  suffix. This is useful for debugging purposes.

       -p pathname	    Specify the directory where the output files will be placed. This option overrides the current working directory.

       -x exclude-file	    Specify  a	 .po  file that contains a list of msgids that are not to be extracted from the input files. The format of
			    exclude-file is identical to the .po file. However, only the msgid directive line in exclude-file is used.	All  other
			    lines are simply ignored.  The -x option can only be used with the -a option.

       -h		    Print a help message on the standard output.

NOTES

       xgettext  is  not  able to extract cast strings, for example ANSI C casts of literal strings to (const char *). This is unnecessary anyway,
       since the prototypes in <libintl.h> already specify this type.

       In messages and translation notes, lines greater than 2048 characters are truncated to 2048 characters and a warning message is printed	to
       stderr.
