IConnectionManager::GetNextConnectionID (Windows CE 5.0)
This iterator method returns a connection ID for a connection managed by this ConnectionManager instance. Subsequent calls to this method return additional connection IDs. Before using this method, call IConnectionManager::GetFirstConnectionID to initialize the iterator and retrieve the first connection ID.
virtual DWORD GetNextConnectionID( long* pConnectionID) = 0;
Parameters
- pConnectionID
[in, out] Pointer to an integer allocated by the caller which this method modifies to contain the next connection ID. Does not correspond directly to a state variable because of use of an iterator model with GetFirstConnectionID. Related to the CurrentConnectionIDs state variable.
Return Values
Custom implementations can return appropriate error codes. Should return SUCCESS_AV if the method succeeds. Otherwise, should return an error code defined in WinError.h or UPnP.h, or one of the UPnP AV-specific return values specified in UPnPAVError.
The implementation of this method in IConnectionManagerImpl returns these errors:
| Value | Description |
|---|---|
| ERROR_AV_POINTER | The pConnectionID pointer is NULL. |
| ERROR_AV_NO_MORE_ITEMS | There are no more connection IDs to return. |
| SUCCESS_AV | The next connection ID was returned. |
Remarks
This method and GetFirstConnectionID combined correspond to the ConnectionManager service's GetCurrentConnectionIDs action.
For more information about the actions in the ConnectionManager service, see UPnP AV DCP Documentation.
