Ok, I'll try them on an ioctl on monday. I'll let you know then.

I was thinking of providing an API similar to v4l2 on my RTDM video
driver. But since it does not have neither mmap nor select/poll, I'll
have to do all these tasks by ioctl... But that is no problem at all.
There will not be missing any feature but the v4l2 compatibility...
Thank you for all support you are giving me.
Best regards,
Rodrigo.
