NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
pcre2_jit_stack *pcre2_jit_stack_create(size_t startsize,
size_t maxsize, pcre2_general_context *gcontext);
DESCRIPTION
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 pcre2_jit_stack_assign() to associate the stack with a
compiled pattern, which can then be processed by pcre2_match() or
pcre2_jit_match(). A maximum stack size of 512KiB to 1MiB should
be more than enough for any pattern. If the stack couldn't be
allocated or the values passed were not reasonable, NULL will be
returned. For more details, see the pcre2jit page.
There is a complete description of the PCRE2 native API in the
pcre2api page and a description of the POSIX API in the
pcre2posix page.
