SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>void pcre2_jit_stack_assign(pcre2_match_context *<i>mcontext</i>,</b>
<b> pcre2_jit_callback <i>callback_function</i>, void *<i>callback_data</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function provides control over the memory used by JIT as a run-time stack
when <b>pcre2_match()</b> or <b>pcre2_jit_match()</b> is called with a pattern
that has been successfully processed by the JIT compiler. The information that
determines which stack is used is put into a match context that is subsequently
passed to a matching function. The arguments of this function are:
<pre>
mcontext a pointer to a match context
callback a callback function
callback_data a JIT stack or a value to be passed to the callback
</PRE>
</P>
<P>
If <i>callback</i> is NULL and <i>callback_data</i> is NULL, an internal 32K
block on the machine stack is used.
</P>
<P>
If <i>callback</i> is NULL and <i>callback_data</i> is not NULL,
<i>callback_data</i> must be a valid JIT stack, the result of calling
<b>pcre2_jit_stack_create()</b>.
</P>
<P>
If <i>callback</i> not NULL, it is called with <i>callback_data</i> as an
argument at the start of matching, in order to set up a JIT stack. If the
result is NULL, the internal 32K stack is used; otherwise the return value must
be a valid JIT stack, the result of calling <b>pcre2_jit_stack_create()</b>.
</P>
<P>
You may safely use the same JIT stack for multiple patterns, as long as they
are all matched in the same thread. In a multithread application, each thread
must use its own JIT stack. For more details, see the
<a href="pcre2jit.html"><b>pcre2jit</b></a>
page.
