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.
|
|
</P>
|
|
<P>
|
|
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 <b>pcre2_jit_match()</b> in UTF mode if you are sure the
|
|
subject 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. Unsupported
|
|
options are ignored.
|
|
</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.
