19     .rs
20     .sp
21     This function is used to create a stack for use by the code compiled by the JIT
22 ph10 868 optimization of \fBpcre[16]_study()\fP. The arguments are a starting size for
23     the stack, and a maximum size to which it is allowed to grow. The result can be
24 ph10 968 passed to the JIT run-time code by \fBpcre[16]_assign_jit_stack()\fP, or that
25 ph10 683 function can set up a callback for obtaining a stack. A maximum stack size of
26 ph10 691 512K to 1M should be more than enough for any pattern. For more details, see
