PCRE2_CODE_FREE 3 "28 June 2018" "PCRE2 10.32"
NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
.rs #include <pcre2.h>

 void pcre2_code_free(pcre2_code *code); 
.
DESCRIPTION
.rs If code is NULL, this function does nothing. Otherwise, code must point to a compiled pattern. This function frees its memory, including any memory used by the JIT compiler. If the compiled pattern was created by a call to pcre2_code_copy_with_tables(), the memory for the character tables is also freed.

There is a complete description of the PCRE2 native API in the HREF
pcre2api
page and a description of the POSIX API in the HREF
pcre2posix
page.
