   Hi,

>>> The check should be against concrete version (0x10000 in this case).

Stepping back: what does the version mean?

0x10000 == 1.0 ?
0x10001 == 1.1 ?

Can I expect the interface stay backward compatible if only the minor 
revision changes, i.e. makes it sense to accept 1.x?

Will the major revision ever change?  Does it make sense to check the 
version at all?

thanks,
   Gerd
