PCRE2_JIT_MATCH(3)	    Library Functions Manual	      PCRE2_JIT_MATCH(3)

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 success-
     fully 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()  ap-
     plies.

     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 sub-
     ject 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.  Unsup-
     ported options are ignored.

     The  return  values  are  the  same  as  for  pcre2_match()  plus PCRE2_ER-
     ROR_JIT_BADOPTION if a matching mode (partial  or	complete)  is  requested
     that  was	not compiled. For details of partial matching, see the pcre2par-
     tial 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.
