PCRE2_MATCH_DATA_FREE(3)   Library Functions Manual   PCRE2_MATCH_DATA_FREE(3)

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 match data block was	previously passed to  pcre2_match(),  it  will
       have an attached	heapframe vector; this is also freed.

       If the PCRE2_COPY_MATCHED_SUBJECT was used for a	successful match using
       this  match  data  block,  the  copy of the subject that	was referenced
       within 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.
