pcre_get_stringnumber

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 complete 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.
