|
|
point to an unsigned long integer. The available codes are:
|
|
<pre>
|
|
PCRE_CONFIG_JIT Availability of just-in-time compiler
|
|

|
|
is also given if PCRE_CONFIG_UTF16 or PCRE_CONFIG_UTF32 is passed to
|
|
<b>pcre_config()</b>, if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF32 is passed to
|
|
<b>pcre16_config()</b>, or if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF16 is passed to
|
|
<b>pcre32_config()</b>.
