NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       int pcre2_set_recursion_memory_management(
         pcre2_match_context *mcontext,
         void *(*private_malloc)(PCRE2_SIZE, void *),
         void (*private_free)(void *, void *), void *memory_data);

DESCRIPTION

       This  function  sets  the match context fields for custom memory management when PCRE2 is compiled to use
       the heap instead of the system stack for recursive function calls while matching. When PCRE2 is  compiled
       to  use  the  stack  (the default) this function does nothing. The first argument is a match context, the
       second and third specify the memory allocation and freeing functions, and the final argument is an opaque
       value that is passed to them whenever they are called. The result of this function is always zero.

       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.
