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.
