SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</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>

DESCRIPTION
</b><br>
<P>
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 <b>pcre2_match()</b> applies.
Its arguments 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. Unsupported
options are ignored. The subject string is not checked for UTF validity.
</P>
<P>
The return values are the same as for <b>pcre2_match()</b> 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
<a href="pcre2partial.html"><b>pcre2partial</b></a>
page.
