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.
