Otherwise, 29<i>match_data</i> must point to a match data block, which this function frees, 30using the memory freeing function from the general context or compiled pattern 31with which it was created, or <b>free()</b> if that was not set. If the match 32data block was previously passed to <b>pcre2_match()</b>, it will have an 33attached heapframe vector; this is also freed. 34</P> 35<P> 36If the PCRE2_COPY_MATCHED_SUBJECT was used for a successful match using this 37match data block, the copy of the subject that was referenced within the block 38is also freed. 39</P> 40<P> 41There is a complete description of the PCRE2 native API in the 42<a href="pcre2api.html"><b>pcre2api</b></a> 43page and a description of the POSIX API in the 44<a href="pcre2posix.html"><b>pcre2posix</b></a> 45page. 46<p> 47Return to the <a href="index.html">PCRE2 index page</a>. 48</p> 49
