PCRE_JIT_STACK_ALLOC
Section: C Library Functions (3) Updated: 24 June 2012 Index
Return to Main Contents
NAME
PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
pcre_jit_stack *pcre_jit_stack_alloc(int startsize,
int maxsize);
pcre16_jit_stack *pcre16_jit_stack_alloc(int startsize,
int maxsize);
pcre32_jit_stack *pcre32_jit_stack_alloc(int startsize,
int maxsize);
DESCRIPTION
This function is used to create a stack for use by the code compiled by the JIT
optimization of pcre[16|32]_study(). The arguments are a starting size for
the stack, and a maximum size to which it is allowed to grow. The result can be
passed to the JIT run-time code by pcre[16|32]_assign_jit_stack(), or that
function can set up a callback for obtaining a stack. A maximum stack size of
512K to 1M should be more than enough for any pattern. For more details, see
the
pcrejit
page.
There is a complete description of the PCRE native API in the
pcreapi
page and a description of the POSIX API in the
pcreposix
page.
