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);

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]_exec() used
	 stringcount   Value returned by pcre[16]_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]_malloc(). The convenience function pcre[16]_free_substring()
       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.
