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);

     int pcre16_get_stringnumber(const pcre16 *code,
	  PCRE_SPTR16 name);

     int pcre32_get_stringnumber(const pcre32 *code,
	  PCRE_SPTR32 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 al-
     lowed (PCRE_DUPNAMES is set), it is not defined which of the numbers is re-
     turned by pcre[16|32]_get_stringnumber(). You can obtain the complete  list
     by calling pcre[16|32]_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.
