       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       int pcre2_substring_number_from_name(const pcre2_code *code,
         PCRE2_SPTR name);

DESCRIPTION

       This  convenience  function  finds  the  number  of a named substring capturing parenthesis in a compiled
       pattern, provided that it is a unique name. The function 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
       PCRE2_ERROR_NOSUBSTRING  if it is not found. When duplicate names are allowed (PCRE2_DUPNAMES is set), if
       the name is not unique, PCRE2_ERROR_NOUNIQUESUBSTRING is returned. You can obtain  the  list  of  numbers
       with the same name by calling pcre2_substring_nametable_scan().

       There  is  a  complete  description of the PCRE2 native API in the pcre2api page and a description of the
       POSIX API in the pcre2posix page.
