PCRE2_SUBS..._FROM_NAME(3) Library Functions Manual PCRE2_SUBS..._FROM_NAME(3)

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 captur-
       ing  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.
