       PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

       int pcre2_jit_compile(pcre2_code *code, uint32_t options);


       This function requests JIT compilation, which, if the just-in-time com-
       piler 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  documenta-

       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 fol-
       lowing 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       has    been    superseded     by     the     pcre2_compile()     option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 exe-
       cutable 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.
