My reading of the docs indicate that event.packet-data is a enet_uint8 *, 
which is typecast from a pointer to char.  This implies that I should be able 
to cast it to void*

void	*buffer;

buffer = (void) event.packet->data;

But this didn't seem to work.  Like I said, I'm a bit rusty...  So I was on 
the right track?  I just have to fiddle with syntax, then.

As to the call to enet_packet_destroy(), yes, I was going to process the 
packet and make that call immediately afterward.
