.SH DESCRIPTION
.rs
.sp
This function is used to create a stack for use by the code compiled by the JIT
compiler. The first two arguments are a starting size for the stack, and a
maximum size to which it is allowed to grow. The final argument is a general
context, for memory allocation functions, or NULL for standard memory
allocation. The result can be passed to the JIT run-time code by calling
2014-10-21 18:33:30 +02:00
\fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern,
2017-03-24 17:53:38 +01:00
which can then be processed by \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP.
A maximum stack size of 512K to 1M should be more than enough for any pattern.
