In "man ioctl" we can read:
The ioctl function manipulates the underlying device
parameters of special files. In particular, many operat�
ing characteristics of character special files (e.g. ter�
minals) may be controlled with ioctl requests. The argu�
ment d must be an open file descriptor.
At http://www.4front-tech.com/pguide/index.html i found OSS
Programmer's guide.
Please correct me if i'm wrong. OSS is what currently is used
in the linux-kernel. There is a new thing called ALSA
http://www.alsa-project.org/ that does not have certain limitiations
that OSS has.
ALSA may replace OSS in the kernel in a near? future.
ALSA is used by many linux audio programmers.
