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.
