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

NAME
       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include	<pcre2.h>

       int pcre2_substring_nametable_scan(const	pcre2_code *code,
	 PCRE2_SPTR name, PCRE2_SPTR *first, PCRE2_SPTR	*last);

DESCRIPTION

       This  convenience function finds, for a compiled	pattern, the first and
       last entries for	a given	name in	 the  table  that  translates  capture
       group names into	numbers.

	 code	 Compiled regular expression
	 name	 Name whose entries required
	 first	 Where to return a pointer to the first	entry
	 last	 Where to return a pointer to the last entry

       When the	name is	found in the table, if first is	NULL, the function re-
       turns  a	group number, but if there is more than	one matching entry, it
       is not defined which one. Otherwise, when both pointers have been  set,
       the yield of the	function is the	length of each entry in	code units. If
       the name	is not found, PCRE2_ERROR_NOSUBSTRING is returned.

       There  is a complete description	of the PCRE2 native API, including the
       format of the table entries, in the pcre2api page, and a	description of
       the POSIX API in	the pcre2posix page.
