PCRE_JIT_STACK_ALLOC(3) Introduction to Library Functions

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.
