Warning - basing this on the OSS API is probably a mistake. Although
ALSA supports the OSS API, its also preferable to use the ALSA API for
a variety of reasons, most of them related to interoperability with
different audio interfaces and user configured I/O configurations.

Please do *NOT* use the OSS API for mmap access. It offers no chance
to interpose a user-space library between the app code and the driver
system, which means that the code will not work in situations where
the user has requested use of a not-purely-hardware device.
