The first two arguments are a starting size for the stack, and a 31 maximum size to which it is allowed to grow. The final argument is a general 32 context, for memory allocation functions, or NULL for standard memory 33 allocation. The result can be passed to the JIT run-time code by calling 34 <b>pcre2_jit_stack_assign()</b> to associate the stack with a compiled pattern, 35 which can then be processed by <b>pcre2_match()</b>. If the "fast path" JIT 36 matcher, <b>pcre2_jit_match()</b> is used, the stack can be passed directly as 37 an argument. A maximum stack size of 512K to 1M should be more than enough for 38 any pattern.
