SYNOPSIS top


       #include <pcre2.h>

       int pcre2_jit_compile(pcre2_code *code, uint32_t options);

DESCRIPTION top


       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

       There is also an obsolete option called PCRE2_JIT_INVALID_UTF,
       which has been superseded by the pcre2_compile() option
       PCRE2_MATCH_INVALID_UTF. The old option is deprecated and may be
       removed in the future.

       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. The function can also return PCRE2_ERROR_NOMEMORY if JIT
       is unable to allocate executable memory for the compiler, even if
       it was because of a system security restriction.

       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.
