Pointer to the portc structure created by the driver.

.SH "DESCRIPTION"
.PP
OSS audio drivers can have three per-audiodevice pointers that the low level
driver can use as it likes. Most drivers use only the common portc structure. However
spme drivers may need to use separate portc structures for recording and playback.
.PP
The driver allocates the port structures when initializing the device and registers them
after installing the audio device. Later the driver can obtain the portc pointer(s) from
OSS.
.PP
.SH "RETURN VALUES"
The get functions return the portc pointer or NULL if no portc pointer has been set.
There are no error returns.
