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.
