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 optimization of pcre[16|32]_study(). The arguments are a
       starting size for the stack, and a maximum 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 description of the POSIX API in the pcreposix page.
