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. 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.
