-Description
------------
-
-This system call opens a named audio device (e.g.
-/dev/dvb/adapter0/audio0) for subsequent use. When an open() call has
-succeeded, the device will be ready for use. The significance of
-blocking or non-blocking mode is described in the documentation for
-functions where there is a difference. It does not affect the semantics
-of the open() call itself. A device opened in blocking mode can later be
-put into non-blocking mode (and vice versa) using the F_SETFL command
-of the fcntl system call. This is a standard system call, documented in
-the Linux manual page for fcntl. Only one user can open the Audio Device
-in O_RDWR mode. All other attempts to open the device in this mode will
-fail, and an error code will be returned. If the Audio Device is opened
-in O_RDONLY mode, the only ioctl call that can be used is
-AUDIO_GET_STATUS. All other call will return with an error code.
