30: DESCRIPTION
31: </b><br>
32: <P>
33: This function provides control over the memory used as a stack at runtime by a
1.1.1.2 ! misho 34: call to <b>pcre[16]_exec()</b> with a pattern that has been successfully
! 35: compiled with JIT optimization. The arguments are:
1.1 misho 36: <pre>
1.1.1.2 ! misho 37: extra the data pointer returned by <b>pcre[16]_study()</b>
1.1 misho 38: callback a callback function
39: data a JIT stack or a value to be passed to the callback
40: function
41: </PRE>
42: </P>
43: <P>
44: If <i>callback</i> is NULL and <i>data</i> is NULL, an internal 32K block on
45: the machine stack is used.
46: </P>
47: <P>
48: If <i>callback</i> is NULL and <i>data</i> is not NULL, <i>data</i> must
1.1.1.2 ! misho 49: be a valid JIT stack, the result of calling <b>pcre[16]_jit_stack_alloc()</b>.
1.1 misho 50: </P>
51: <P>
52: If <i>callback</i> not NULL, it is called with <i>data</i> as an argument at
53: the start of matching, in order to set up a JIT stack. If the result is NULL,
54: the internal 32K stack is used; otherwise the return value must be a valid JIT
1.1.1.2 ! misho 55: stack, the result of calling <b>pcre[16]_jit_stack_alloc()</b>.
1.1 misho 56: </P>
57: <P>
58: You may safely assign the same JIT stack to multiple patterns, as long as they
59: are all matched in the same thread. In a multithread application, each thread
60: must use its own JIT stack. For more details, see the
61: <a href="pcrejit.html"><b>pcrejit</b></a>
62: page.
