.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

\fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern,

which can then be processed by \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP.

A maximum stack size of 512KiB to 1MiB should be more than enough for any

pattern. For more details, see the
