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.
