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.
