30DESCRIPTION
31</b><br>
32<P>
33This function is used to create a stack for use by the code compiled by the JIT
34optimization of <b>pcre[16]_study()</b>. The arguments are a starting size for
35the stack, and a maximum size to which it is allowed to grow. The result can be
36passed to the JIT run-time code by <b>pcre[16]_assign_jit_stack()</b>, or that
37function can set up a callback for obtaining a stack. A maximum stack size of
38512K to 1M should be more than enough for any pattern. For more details, see
