pcre_jit_stack_alloc (3)

Name

pcre_jit_stack_alloc - 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

PCRE_JIT_STACK_ALLOC(3)    Library Functions Manual    PCRE_JIT_STACK_ALLOC(3)



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 start-
       ing  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.
