<H2>DESCRIPTION</H2>
|
|
|
|
|
|
<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
|
|
|
|
<B>pcre2jit</B>
|
|
|
|
documentation.
|
|
<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:
|
|
<P>
|
|
<BR> PCRE2_JIT_COMPLETE compile code for full matching
|
|
<BR> PCRE2_JIT_PARTIAL_SOFT compile code for soft partial matching
|
|
<BR> PCRE2_JIT_PARTIAL_HARD compile code for hard partial matching
|
|
<P>
|
|
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superseded by the 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>
|
|
|
|
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.
|
|
<P>
|
|
|
|
There is a complete description of the PCRE2 native API in the
|
|
|
|
<B>pcre2api</B>
|
|
|
|
page and a description of the POSIX API in the
|
|
|
|
<B>pcre2posix</B>
|
|
|
|
page.
