pcre2_jit_stack_create(3) Library Functions Manual pcre2_jit_stack_create(3)
NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
pcre2_jit_stack_create(3) 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.
