DESCRIPTION
|

|
</b><br>
|
||
|
|
<P>
|
||
|
|
This function requests JIT compilation, which, if the just-in-time compiler is
|
||
|
|
available, further processes a compiled pattern into machine code that executes
|
||
|
|
much faster than the <b>pcre2_match()</b> interpretive matching function. Full
|
||
|
|
details are given in the
|
||
|
|
<a href="pcre2jit.html"><b>pcre2jit</b></a>
|
||
|
|
documentation.
|
||
|
|
</P>
|
||
|
|
<P>
|
||
|
|
The first argument is a pointer that was returned by a successful call to
|
||
|
|
<b>pcre2_compile()</b>, and the second must contain one or more of the following
|
||
|
|
bits:
|
||
|
|
<pre>
|
||
|
|
PCRE2_JIT_COMPLETE compile code for full matching
|
||
|
|
PCRE2_JIT_PARTIAL_SOFT compile code for soft partial matching
|
||
|
|
PCRE2_JIT_PARTIAL_HARD compile code for hard partial matching
|
||
|
|
</pre>
|
||
|
|
There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been
|
||
|
|
superseded by the <b>pcre2_compile()</b> option PCRE2_MATCH_INVALID_UTF. The old
|
||
|
|
option is deprecated and may be removed in the future.
|
||
|
|
</P>
|
||
|
|
<P>
|
||
|
|
The yield of the function is 0 for success, or a negative error code otherwise.
|
||
|
|
In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or
|
||
|
|
if an unknown bit is set in <i>options</i>. The function can also return
|
||
|
|
PCRE2_ERROR_NOMEMORY if JIT is unable to allocate executable memory for the
|
||
|
|
compiler, even if it was because of a system security restriction.
