need help in writing a device driver
Hi!
I am new to writing device drivers, and I would need to write one like this:
Write a driver similar to the one with a circular buffer, this time blocking on a full buffer. Additio- nally the driver shall notify a program after an empty buffer received some bytes, so the program knows, there is something to read.
Can anybody help me?
Thx: Gogo

Welcome to the forums!
This looks like a homework question... is it?
What have you written so far?
You can check this online book for some tips and advice about your device driver questions.

Well, I haven't gone far yet. I don't really understand the difference between the circular fubber and full buffer.
