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. If the stack couldn't be allocated or the values passed were not 38reasonable, NULL will be returned.
