dinput cleanup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

originally I tried to debug why some game's cursor was stuck in the middle,
but I couldn't find it out properly (due to incomprehensible warping magic).
This is said to be broken since moving the code from direct X11 addressing
to USER driver addressing.

- apply some small cleanups to dinput mouse code
