.SH "DESCRIPTION"
.PP
The devc pointer of an audio device points to the data structure where the driver
stores it's per-card information. The driver can store a pointer to this structure
in the audio device and obtain it later in the callback functions.
Usually the driver sets the devc pointer when calling ossddk_install_audiodev. However
it is possible to change this pointer later with this function.
