The property descriptor (instance data) consists of a KSPROPERTY structure followed by a ULONG variable containing a device ID that identifies a virtual audio device. If SysAudio enumerates n virtual audio devices (see KSPROPERTY_SYSAUDIO_DEVICE_COUNT), then valid device IDs range from 0 to n-1. Also, a device ID value of -1 can be used to indicate the current device, which is the last virtual audio device opened by a KSPROPERTY_SYSAUDIO_DEVICE_INSTANCE or KSPROPERTY_SYSAUDIO_INSTANCE_INFOset-property request.
The property value (operation data) is a pointer to a null-terminated string of Unicode characters that contains the device's interface name.
Return Value
A KSPROPERTY_SYSAUDIO_DEVICE_INTERFACE_NAME property request returns STATUS_SUCCESS to indicate that it has completed successfully. Otherwise, the request returns an appropriate error status code.
