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 optimiza‐
       tion of pcre[16|32]_study(). The arguments are a starting size for the stack, and a  maxi‐
       mum 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  descrip‐
       tion of the POSIX API in the pcreposix page.
