+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.
