.sp
.ne 2
.mk
\fB\fIvers\fR
.in +16n
.rt
The OSSDDK mixer interface version. Pass OSS_MIXER_DRIVER_VERSION in this parameter.
.in -16n
.sp
.ne 2
.mk
\fB\fIosdev\fR
.in +16n
.rt
OSS device handle from ossddk_register_device(9ossddk).
.in -16n
.sp
.ne 2
.mk
\fB\fImaster_osdev\fR
.in +16n
.rt
OSS device handle for the master device. Usually same as \fIosdev\fR but
virtual drivers have to give the osdev handle of the master/physical device here.
OSS uses this parameter for example to get the right iblock_cookie.

.ne 2
.mk
\fB\fIname\fR
.in +16n
.rt
Name of the mixer device to be shown in /dev/sndstat. Also returned by the 
SNDCTL_MIXERINFO(2oss) ioctl call.
.in -16n

\fB\fIdriver\fR
.in +16n
.rt
Pointer to the mixer driver callback table (mixer_driver_t).
.in -16n

.mk
\fB\fIdriver_size\fR
.in +16n
.rt
Set to sizeof(mixer_driver_t).
