SYNOPSIS
 

#include &#60;pcre2.h&#62;


int pcre2_jit_compile(pcre2_code *code, uint32_t options);

 
DESCRIPTION
 

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 pcre2_match() interpretive matching function. Full
details are given in the
<a href="pcre2jit.html">pcre2jit</a>
documentation.


The first argument is a pointer that was returned by a successful call to
pcre2_compile(), 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>
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 options.


There is a complete description of the PCRE2 native API in the
<a href="pcre2api.html">pcre2api</a>
page and a description of the POSIX API in the
<a href="pcre2posix.html">pcre2posix</a>
page.
