dwOptions

One of the PHONEINITIALIZEEXOPTION_ constants. Specifies the event notification mechanism the application desires to use.

hEvent

If dwOptions specifies PHONEINITIALIZEEXOPTION_USEEVENT, TAPI returns the event handle in this field.

hCompletionPort

If dwOptions specifies PHONEINITIALIZEEXOPTION_USECOMPLETIONPORT, the application must specify in this field the handle of an existing completion port opened using CreateIoCompletionPort.

dwCompletionKey

If dwOptions specifies PHONEINITIALIZEEXOPTION_USECOMPLETIONPORT, the application must specify in this field a value that will be returned through the lpCompletionKey parameter of GetQueuedCompletionStatus to identify the completion message as a telephony message.
