PCRE2_SUBSTRING_NUMBER_FROM_NAME(3)           FreeBSD Library Functions Manual

NAME
       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.
