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.  Its
       arguments are exactly the same as for pcre2_match().

       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 subject string is not
       checked for UTF validity.

       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.
