NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       int pcre2_jit_compile(pcre2_code *code, uint32_t options);

DESCRIPTION

       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       There  is  also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been superseded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.
