NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       void pcre2_match_data_free(pcre2_match_data *match_data);

DESCRIPTION

       If  match_data  is  NULL,  this  function  does nothing. Otherwise, match_data must point to a match data
       block, which this function frees, using the memory freeing function from the general context or  compiled
       pattern with which it was created, or free() if that was not set.

       If  the  PCRE2_COPY_MATCHED_SUBJECT was used for a successful match using this match data block, the copy
       of the subject that was remembered with the block is also freed.

       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.
