Manual
PCRE2_SUBSTRING_LENGTH_BYNUMBER
NAMESYNOPSIS
DESCRIPTION
NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
int
pcre2_substring_length_bynumber(pcre2_match_data
*
match_data
,
uint32_t
number
, PCRE2_SIZE
*
length
);
DESCRIPTION
This function returns the length of a matched substring, identified by number. The arguments are:
match_data
The match data block for the match
number
The substring number
length
Where to return the length, or NULL
The third argument may be NULL if all you want to know is whether or not a substring is set. The yield is zero on success, or a negative error code otherwise. After a partial match, only substring 0 is available.
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.
