It is a "fast path" interface to JIT, and 34it bypasses some of the sanity checks that <b>pcre2_match()</b> applies. 35</P> 36<P> 37In UTF mode, the subject string is not checked for UTF validity. Unless 38PCRE2_MATCH_INVALID_UTF was set when the pattern was compiled, passing an 39invalid UTF string results in undefined behaviour. Your program may crash or 40loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you 41should only call <b>pcre2_jit_match()</b> in UTF mode if you are sure the 42subject is valid. 43</P> 44<P> 45The arguments for <b>pcre2_jit_match()</b> are exactly the same as for 46<a href="pcre2_match.html"><b>pcre2_match()</b>,</a> 47except that the subject string must be specified with a length; 48PCRE2_ZERO_TERMINATED is not supported. 49</P> 50<P> 51The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, 52PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupported 53options are ignored. 54</P> 55<P> 56The return values are the same as for <b>pcre2_match()</b> plus 57PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is requested 58that was not compiled.
