It was generatedautomatically from the original man page. If there is any nonsense in it,please consult the man page, in case the conversion went wrong.<br><br><b>SYNOPSIS</b><br><P><b>#include <pcre2.h></b></P><P><b>int pcre2_jit_match(const pcre2_code *<i>code</i>, PCRE2_SPTR <i>subject</i>,</b><b> PCRE2_SIZE <i>length</i>, PCRE2_SIZE <i>startoffset</i>,</b><b> uint32_t <i>options</i>, pcre2_match_data *<i>match_data</i>,</b><b> pcre2_match_context *<i>mcontext</i>);</b></P><br><b>DESCRIPTION</b><br><P>This function matches a compiled regular expression that has been successfullyprocessed by the JIT compiler against a given subject string, using a matchingalgorithm that is similar to Perl's. It is a "fast path" interface to JIT, andit bypasses some of the sanity checks that <b>pcre2_match()</b> applies.</P><P>In UTF mode, the subject string is not checked for UTF validity. UnlessPCRE2_MATCH_INVALID_UTF was set when the pattern was compiled, passing aninvalid UTF string results in undefined behaviour. Your program may crash orloop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF youshould only call <b>pcre2_jit_match()</b> in UTF mode if you are sure thesubject is valid.</P><P>The arguments for <b>pcre2_jit_match()</b> are exactly the same as for<a href="pcre2_match.html"><b>pcre2_match()</b>,</a>except that the subject string must be specified with a length;PCRE2_ZERO_TERMINATED is not supported.</P><P>The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupportedoptions are ignored.</P><P>The return values are the same as for <b>pcre2_match()</b> plusPCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is requestedthat was not compiled. For details of partial matching, see the<a href="pcre2partial.html"><b>pcre2partial</b></a>page.</P><P>There is a complete description of the PCRE2 native API in the<a href="pcre2api.html"><b>pcre2api</b></a>page and a description of the JIT API in the<a href="pcre2jit.html"><b>pcre2jit</b></a>page.<p>Return to the <a href="index.html">PCRE2 index page</a>.</p>
