SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>int pcre2_set_compile_recursion_guard(pcre2_compile_context *<i>ccontext</i>,</b>
<b> int (*<i>guard_function</i>)(uint32_t));</b>

DESCRIPTION
</b><br>
<P>
This function defines, within a compile context, a function that is called
whenever <b>pcre2_compile()</b> starts to compile a parenthesized part of a
pattern. The argument to the function gives the current depth of parenthesis
nesting. The function should return zero if all is well, or non-zero to force
an error. This feature is provided so that applications can check the available
system stack space, in order to avoid running out. The result of this function
is always zero.
</P>
