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 er-
       ror code otherwise. After a partial match, only substring 0  is  avail-
       able.

       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.
