DESCRIPTION

       This  function matches a compiled regular expression that has been suc-
       cessfully studied with one of the JIT options against a  given  subject
       string,  using  a matching algorithm that is similar to Perl's. It is a
       "fast path" interface to JIT, and it bypasses some of the sanity checks
       that  pcre_exec()  applies.  It returns offsets to captured substrings.
       Its arguments are:

         code         Points to the compiled pattern
         extra        Points to an associated pcre[16|32]_extra structure,
                        or is NULL
         subject      Points to the subject string
         length       Length of the subject string, in bytes
         startoffset  Offset in bytes in the subject at which to
                        start matching
         options      Option bits
         ovector      Points to a vector of ints for result offsets
         ovecsize     Number of elements in the vector (a multiple of 3)
         jstack       Pointer to a JIT stack

       The allowed options are:

         PCRE_NOTBOL            Subject string is not the beginning of a line
         PCRE_NOTEOL            Subject string is not the end of a line
         PCRE_NOTEMPTY          An empty string is not a valid match
         PCRE_NOTEMPTY_ATSTART  An empty string at the start of the subject
                                  is not a valid match
         PCRE_NO_UTF16_CHECK    Do not check the subject for UTF-16
                                  validity (only relevant if PCRE_UTF16
                                  was set at compile time)
         PCRE_NO_UTF32_CHECK    Do not check the subject for UTF-32
                                  validity (only relevant if PCRE_UTF32
                                  was set at compile time)
         PCRE_NO_UTF8_CHECK     Do not check the subject for UTF-8
                                  validity (only relevant if PCRE_UTF8

         match_limit      Limit on internal resource use
         match_limit_recursion  Limit on internal recursion depth
         callout_data     Opaque data passed back to callouts
         tables           Points to character tables or is NULL
         mark             For passing back a *MARK pointer
         executable_jit   Opaque data from JIT compilation

       The  flag  bits  are   PCRE_EXTRA_STUDY_DATA,   PCRE_EXTRA_MATCH_LIMIT,
       PCRE_EXTRA_MATCH_LIMIT_RECURSION,              PCRE_EXTRA_CALLOUT_DATA,
       PCRE_EXTRA_TABLES, PCRE_EXTRA_MARK and PCRE_EXTRA_EXECUTABLE_JIT.
