IWMSBroadcastPublishingPoint::get_BroadcastStatus
The get_BroadcastStatus method retrieves an enumeration value that indicates the status of the broadcast publishing point.
Syntax
HRESULT get_BroadcastStatus( WMS_BROADCAST_PUBLISHING_POINT_STATUS* pVal );
Parameters
pVal
[out] Member of a WMS_BROADCAST_PUBLISHING_POINT_STATUS enumeration type that indicates the status of the publishing point. This must be one of the following values.
| Value | Description |
| WMS_BROADCAST_PUBLISHING_POINT_STOPPED | The publishing point is not currently running. |
| WMS_BROADCAST_PUBLISHING_POINT_STARTED_WITHOUT_DATA | The publishing point has been initialized and the multicast data sinks are transmitting multicast beacons. |
| WMS_BROADCAST_PUBLISHING_POINT_STARTED | The publishing point is running. |
| WMS_BROADCAST_PUBLISHING_POINT_ARCHIVING | The publishing point is archiving content to a file. |
| WMS_BROADCAST_PUBLISHING_POINT_CHANGE_IN_PROGRESS | The publishing point is starting. |
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
| Return code | Number | Description |
| E_POINTER | 0x80004003 | pVal is a NULL pointer argument. |
| NS_E_PUBLISHING_POINT_REMOVED | 0xC00D145AL | The publishing point has already been removed. |
