Writing for OSS is a constraint, not a choice. I'm not
starting from scratch there is some older driver that
I have to port, and it's been written for OSS. Later
if there is time for it I will make the ALSA
I've read docs about doing kernel drivers so my
questions are not general about drivers, but really
directed at audio drivers. I didn't find any resource
about it. The OSS doc seems to be directed to the user
of the API and not for the driver developer.
For example, which function from the file operations
structure have to be implemented and for what purpose
in the case of audio?
