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_compile(pcre2_code *<i>code</i>, uint32_t <i>options</i>);</b></P><br><b>DESCRIPTION</b><br><P>This function requests JIT compilation, which, if the just-in-time compiler isavailable, further processes a compiled pattern into machine code that executesmuch faster than the <b>pcre2_match()</b> interpretive matching function. Fulldetails 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 followingbits:<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 beensuperseded by the <b>pcre2_compile()</b> option PCRE2_MATCH_INVALID_UTF. The oldoption 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 orif an unknown bit is set in <i>options</i>. The function can also returnPCRE2_ERROR_NOMEMORY if JIT is unable to allocate executable memory for thecompiler, even if it was because of a system security restriction.</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 POSIX API in the<a href="pcre2posix.html"><b>pcre2posix</b></a>page.<p>Return to the <a href="index.html">PCRE2 index page</a>.</p>
