- .TH PCRE2_MATCH_DATA_FREE 3 "18 January 2023" "PCRE2 10.43"
- .SH NAME
- PCRE2 - Perl-compatible regular expressions (revised API)
- .SH SYNOPSIS
- .rs
- .sp
- .B #include <pcre2.h>
- .PP
- .nf
- .B void pcre2_match_data_free(pcre2_match_data *\fImatch_data\fP);
- .fi
- .
- .SH DESCRIPTION
- .rs
- .sp
- If \fImatch_data\fP is NULL, this function does nothing. Otherwise,
- \fImatch_data\fP 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 \fBfree()\fP if that was not set. If the match
- data block was previously passed to \fBpcre2_match()\fP, it will have an
- attached heapframe vector; this is also freed.
- .P
- 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.
- .P
- There is a complete description of the PCRE2 native API in the
- .\" HREF
- \fBpcre2api\fP
- .\"
- page and a description of the POSIX API in the
- .\" HREF
- \fBpcre2posix\fP
- .\"
- page.
