I've just finished porting Microwindows to an r&d cable set-top box. You
guys have done some great work with this system!
Because I'm overlaying microwindows on the tv picture, I have some special
needs. My apps need to make some custom calls to the video card, and the
driver has the necessary handles and pointers. I need something like an
ioctl call where I can define my own control codes and pass some custom
data.
Are there any plans to extend SCREENDEVICE to allow this? I realize that
marshalling anything but primitive data types to an out-of-process X server
would be complicated. How about an ioctl-like call for in-process servers
only?
The only hack solution I have now is to use an in-process X server and
extern some global variables to get the necessary handles.
