Return Value

A value of the IUccMediaDevice** (IUccMediaDevice, for a .NET application) type. The successful result points to the selected device.

Win32 COM/C++ Syntax

HRESULT GetSelectedDevice
(
   UCC_AUDIO_VIDEO_DEVICE_CATEGORY enDeviceCategory,
   UCC_MEDIA_TYPES enMediaType,
   UCC_MEDIA_DIRECTIONS enMediaDirection,
   IUccMediaDevice** ppMediaDevice
);

Note

In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API .
