PCRE_GET_STRINGNUMBER(3)				     Library Functions Manual					  PCRE_GET_STRINGNUMBER(3)

NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

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

DESCRIPTION

       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  com-
       plete list by calling pcre_get_stringtable_entries().

       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.
