I was über lazy at first, so took libs from SM. But actually it's quite easy to compile, so let's update to latest version \o/.

DESCRIPTION
|
|
</b><br>
|
|
<P>
|
|
This function provides control over the memory used as a stack at run-time by a
|
|
call to <b>pcre[16|32]_exec()</b> with a pattern that has been successfully
|
|
compiled with JIT optimization. The arguments are:
|
|
<pre>
|
|
extra the data pointer returned by <b>pcre[16|32]_study()</b>
|
|
callback a callback function
|
|
data a JIT stack or a value to be passed to the callback
|
|
function
|
|
</PRE>
|
|
</P>
|
|
<P>
|
|
If <i>callback</i> is NULL and <i>data</i> is NULL, an internal 32K block on
|
|
the machine stack is used.
|
|
</P>
|
|
<P>
|
|
If <i>callback</i> is NULL and <i>data</i> is not NULL, <i>data</i> must
|
|
be a valid JIT stack, the result of calling <b>pcre[16|32]_jit_stack_alloc()</b>.
|
|
</P>
|
|
<P>
|
|
If <i>callback</i> not NULL, it is called with <i>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>pcre[16|32]_jit_stack_alloc()</b>.
|
|
</P>
|
|
<P>
|
|
You may safely assign the same JIT stack to 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="pcrejit.html"><b>pcrejit</b></a>
|
|
page.
