<b>#include &#60;pcre2.h&#62;</b>

<P>
<b>int pcre2_set_recursion_memory_management(</b>
<b> pcre2_match_context *<i>mcontext</i>,</b>

<b> void (*<i>private_free</i>)(void *, void *), void *<i>memory_data</i>);</b>

DESCRIPTION
</b><br>
<P>
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.
