NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre_get_named_substring(const pcre *code,
	    const char *subject, int *ovector,
	    int stringcount, const char *stringname,
	    const char **stringptr);

       int pcre16_get_named_substring(const pcre16 *code,
	    PCRE_SPTR16 subject, int *ovector,
	    int stringcount, PCRE_SPTR16 stringname,
	    PCRE_SPTR16 *stringptr);

       int pcre32_get_named_substring(const pcre32 *code,
	    PCRE_SPTR32 subject, int *ovector,
	    int stringcount, PCRE_SPTR32 stringname,
	    PCRE_SPTR32 *stringptr);

DESCRIPTION

       This is a convenience function for extracting a captured substring by name. The arguments are:

	 code	       Compiled pattern
	 subject       Subject that has been successfully matched
	 ovector       Offset vector that pcre[16|32]_exec() used
	 stringcount   Value returned by pcre[16|32]_exec()
	 stringname    Name of the required substring
	 stringptr     Where to put the string pointer

       The  memory  in	which  the substring is placed is obtained by calling pcre[16|32]_malloc(). The convenience function pcre[16|32]_free_sub-
       string() can be used to free it when it is no longer needed. The  yield	of  the  function  is  the  length  of	the  extracted	substring,
       PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or PCRE_ERROR_NOSUBSTRING if the string name is invalid.

       There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page.
