PCRE2_JIT_STACK_CREATE(3)  Library Functions Manual  PCRE2_JIT_STACK_CREATE(3)

NAME
       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include	<pcre2.h>

       pcre2_jit_stack *pcre2_jit_stack_create(size_t startsize,
	 size_t	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 ar-
       gument 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 re-
       turned. 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.
