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