No, but I'll try to get it right. libXi and libXtst use Device*. Device 
Id's are used over the wire (because pointers lose their meaning across 
processes), which is done transparently by libX*.

The fact that xextproto contains  a library header seems somewhat odd to 
me, I guess it's historical.
