       PCRE - Perl-compatible regular expressions


       #include <pcre.h>

       int pcre_get_stringnumber(const pcre *code,
	    const char *name);


       This convenience function finds the number of a named substring capturing parenthesis in a
       compiled pattern. Its arguments are:

	 code	 Compiled regular expression
	 name	 Name whose number is required

       The yield of the function is the number of the  parenthesis  if	the  name  is  found,  or
       PCRE_ERROR_NOSUBSTRING otherwise. When duplicate names are allowed (PCRE_DUPNAMES is set),
       it is not defined which of the numbers is returned  by  pcre_get_stringnumber().  You  can
       obtain the complete list by calling pcre_get_stringtable_entries().

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