SYNOPSIS top


       #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 top


       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.
