You could/should use the GenericCallback (specifically UnsignedCallback) mechanism here. Look around for examples. And probably your API (which oddly, I don't see here) should let people provide a block/function to call back (look at WKPageForceRepaint for an example, though that one doesn't return a value).

<span class="quote">&gt; Source/WebKit2/WebProcess/WebPage/WebPage.h:753
&gt; +    void getIsMediaElementPaused(uint64_t, uint64_t);</span >

No &quot;get&quot; here; we usually reserve that for functions with out arguments.</pre>
