ILMDVRSink::CreateEvents

#include "ILMDVRSink.h"

C Syntax	HRESULT ILMDVRSink__CreateEvents(pILMDVRSink, nRegistrationID, TargetProcessID, pDataWrittenEvent, pRecordingListChangedEvent)
C++ Syntax	HRESULT CreateEvents(nRegistrationID, TargetProcessID, pDataWrittenEvent, pRecordingListChangedEvent)

ILMDVRSink *pILMDVRSink ;	/* pointer to an interface */
long nRegistrationID;	/* events registration id */
long TargetProcessID;	/* process id of subscriber. */
OLE_HANDLE * pDataWrittenEvent;	/* pointer to handle a data write event */
OLE_HANDLE * pRecordingListChangedEvent;	/* pointer to handle a list changed event */

Creates the windows event objects used by the DVRSink to signal data write and recording list changed events.

Parameter	Description
pILMDVRSink	Pointer to an ILMDVRSink interface.
nRegistrationID	A unique identifier for this event registration.
TargetProcessID	The process id of the event subscriber.
pDataWrittenEvent	Pointer to a handle for the write event.
pRecordingListChangedEvent	Pointer to a handle for the list changed event.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

Whenever data is written to a buffer file, the windows event for the returned write event handle will be set. Likewise, when a buffer file is created or closed, the windows event for the list changed event handle will be set.

Returns S_OK if successful, otherwise a return code indicating the reason for failure:

E_OUTOFMEMORY = Memory allocation error was encountered.
