- Description
The TDx_DrawVideoPortContainer::GetVideoPortConnectInfo method will retrieve connection information from the specified video port. Before calling this method, make sure to setup the TDDVideoPortConnect multiwrapper component with appropriate data.
If the method call fails, the OnError event will be triggered with one of the following values:
DSERR_INVALIDPARAM
DSERR_OUTOFMEMORY
- Parameters
PortId
The PortId parameter defines the ID of the video port for which connection information is to be retrieved.
NumEntries
The NumEntries parameter references the size of the array referenced by the ConnectInfo parameter of this method.
When this value is less than the total connections, the array is filled, this parameter is set to the total number of connections and DDERR_MOREDATA returned in both fErrorValue and the OnError() event.
ConnectInfo
The ConnectInfo parameter references a TDDVideoPortConnect multiwrapper component used for holding the retrieved connection information if this method returns successfully.
When this parameter is NULL, the NumEntries parameter of this component will be set to the total number of connections supported and true returned.
