14 .SH DESCRIPTION
15 .rs
16 .sp
17 This function is used to create a stack for use by the code compiled by the JIT
18 optimization of \fBpcre_study()\fP. The arguments are a starting size for the
19 stack, and a maximum size to which it is allowed to grow. The result can be
20 passed to the JIT runtime code by \fBpcre_assign_jit_stack()\fP, or that
21 function can set up a callback for obtaining a stack. A maximum stack size of
22 512K to 1M should be more than enough for any pattern. For more details, see
23 the
