Interfacing with hardware

by Simmons (no login)


I'm just starting to read up on IOCTL, can anyone point me towards some resources for programming some really hardcore hardware C++ code?

I like the idea that in linux, I can just open the device and start doing stuff with it. If linux can really make this easier, you might just make a believer out of me yet. (Specifically video capture devices)
