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.
