#include <pcre2.h>

int pcre2_jit_compile(pcre2_code *code, uint32_t options);


This function requests JIT compilation, which, if the just-in-time compiler is available, further processes a compiled pattern into machine code that executes much faster than the pcre2_match() interpretive matching function. Full details are given in the pcre2jit documentation.

The first argument is a pointer that was returned by a successful call to pcre2_compile(), and the second must contain one or more of the following bits:

  PCRE2_JIT_COMPLETE      compile code for full matching
  PCRE2_JIT_PARTIAL_SOFT  compile code for soft partial matching
  PCRE2_JIT_PARTIAL_HARD  compile code for hard partial matching
  PCRE2_JIT_INVALID_UTF   compile code to handle invalid UTF
The yield of the function is 0 for success, or a negative error code otherwise. In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or if an unknown bit is set in options.

There is a complete description of the PCRE2 native API in the pcre2api page and a description of the POSIX API in the pcre2posix page.
