NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       pcre2_jit_stack *pcre2_jit_stack_create(PCRE2_SIZE startsize,
         PCRE2_SIZE maxsize, pcre2_general_context *gcontext);

DESCRIPTION

       This  function is used to create a stack for use by the code compiled by the JIT compiler.
       The first two arguments are a starting size for the stack, and a maximum size to which  it
       is  allowed  to  grow.  The  final  argument  is  a general context, for memory allocation
       functions, or NULL for standard memory allocation. The result can be  passed  to  the  JIT
       run-time  code  by calling pcre2_jit_stack_assign() to associate the stack with a compiled
       pattern, which can then be processed by pcre2_match()  or  pcre2_jit_match().   A  maximum
       stack  size  of  512KiB  to  1MiB should be more than enough for any pattern. If the stack
       couldn't be allocated or the values passed were not reasonable, NULL will be returned. For
       more details, see the pcre2jit page.

       There  is  a  complete  description  of  the  PCRE2  native API in the pcre2api page and a
       description of the POSIX API in the pcre2posix page.
