Yes. But we certainly have to define an in/out variable to pass and
hold a value referenced by the void pointer. I have opted for an
unsigned int, http://cool.haxx.se/cvs.cgi/curl/ares/setup_once.h.diff?r1=1.29&r2=1.30

This should be good enough, as long as the internal implementation of
recvfrom functions with a void pointer prototype for sixth argument
use an int or unsigned int.

Thanks,
