Hello,

I am working on LCD module and I want to implement two overlay windows
on frame buffer. I have some queries related to this:

1. Can any buddy suggest me how to proceed towards it??
2. Is their any standard way to use frame buffer ioctl calls??
3. If i have to define my own ioctls then how application manage it??


Thanks and Regards
Vipul Samar
