SYNOPSIS top


       #include <pcre2.h>

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

DESCRIPTION top


       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.
