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::GetFirstConnectionIDto initialize the iterator and retrieve the first connection ID.

Syntax 

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 Value

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 IConnectionManagerImplreturns these errors:

Value Description

ERROR_AV_POINTER

The pConnectionIDpointer 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 GetFirstConnectionIDcombined correspond to the ConnectionManager service's GetCurrentConnectionIDs action.

For more information about the actions in the ConnectionManager service, see UPnP AV DCP Documentation.
