The first two arguments are a starting size for the stack, and a 31maximum size to which it is allowed to grow. The final argument is a general 32context, for memory allocation functions, or NULL for standard memory 33allocation. 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, 35which can then be processed by <b>pcre2_match()</b> or <b>pcre2_jit_match()</b>. 36A maximum stack size of 512KiB to 1MiB should be more than enough for any 37pattern.
