NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       int pcre2_jit_match(const pcre2_code *code, PCRE2_SPTR subject,
         PCRE2_SIZE length, PCRE2_SIZE startoffset,
         uint32_t options, pcre2_match_data *match_data,
         pcre2_match_context *mcontext);

DESCRIPTION

       This  function  matches  a  compiled  regular  expression that has been successfully processed by the JIT
       compiler 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 pcre2_match() applies.

       In  UTF  mode, the subject string is not checked for UTF validity. Unless PCRE2_MATCH_INVALID_UTF was set
       when the pattern was compiled, passing an invalid UTF string results in undefined behaviour. Your program
       may crash or loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you should  only  call
       pcre2_jit_match() in UTF mode if you are sure the subject is valid.

       The  arguments  for  pcre2_jit_match() are exactly the same as for pcre2_match(), except that the subject
       string must be specified with a length; PCRE2_ZERO_TERMINATED is not supported.

       The  supported  options   are   PCRE2_NOTBOL,   PCRE2_NOTEOL,   PCRE2_NOTEMPTY,   PCRE2_NOTEMPTY_ATSTART,
       PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupported options are ignored.

       The  return  values  are  the same as for pcre2_match() plus PCRE2_ERROR_JIT_BADOPTION if a matching mode
       (partial or complete) is requested that was not compiled.  For  details  of  partial  matching,  see  the
       pcre2partial page.

       There is a complete description of the PCRE2 native API in the pcre2api page and a description of the JIT
       API in the pcre2jit page.
