The get_Event method gets the call media event indicator.

HRESULT get_Event(
[out] CALL_MEDIA_EVENT *pCallMediaEvent
);
Parameters
[out] pCallMediaEvent
Pointer to CALL_MEDIA_EVENT indicator.
Return value
This method can return one of these values.
| Return code | Description |
|---|---|
|
Method succeeded. |
|
Insufficient memory exists to perform the operation. |
|
The pCallMediaEvent parameter is not a valid pointer. |
Remarks
Call media events are a crucial indicator of whether certain operations can be performed. For example, when IVideoWindow is exposed on the Terminal object, until the CME_STREAM_ACTIVE is received only the put_Visible method will succeed. For more information about IVideoWindow and put_Visible, see the DirectX documentation.
