IDeferredCommand interface

The IDeferredCommand interface cancels or modify graph-control commands that were queued using the IQueueCommand interface.

When an application calls an IQueueCommand method on the Filter Graph Manager, it receives a pointer to the IDeferredCommand interface. The application can use the interface to cancel or postpone the command, or retrieve the return value from the command.
