The End3 method is called by Windows Media Device Manager to indicate that an operation has finished. This method extends IWMDMProgress2::End2 by providing additional input parameters for the identification (ID) of the event and for a pointer to the context of the commands.

Syntax

HRESULT End3(GUIDEventId,HRESULThrCompletionCode,
  OPAQUECOMMAND*pContext);

Parameters

EventId

[in]  A GUID specifying the event that is ending. Possible values are shown in the following table.

Event Description
SCP_EVENTID_ACQSECURECLOCK Windows Media Device Manager is acquiring a secure clock from server.
SCP_EVENTID_NEEDTOINDIV The device is being individualized. This is not currently used.
SCP_EVENTID_DRMINFO This event ID is used to notify the application with the version DRM header found in the content for each file.

The OPAQUECOMMAND structure returned has the guidCommand member set to SCP_PARAMID_DRMVERSION.

In addition, the data specifies one of the following flags:

WMDM_SCP_DRMINFO_NOT_DRMPROTECTED

WMDM_SCP_DRMINFO_V1HEADER

WMDM_SCP_DRMINFO_V2HEADER
EVENT_WMDM_CONTENT_TRANSFER Content is being transferred to or from the device.

hrCompletionCode

[in]  HRESULT specifying the completion code of the operation that was in progress. The hrCompletionCode parameter is the return code of the operation that ended. This parameter can be any HRESULT, including standard COM error codes, Win32 error codes converted to HRESULT, or Windows Media Device Manager error codes.

pContext

[in, out]  Pointer to an OPAQUECOMMAND structure containing a command sent directly to the device without being handled by Windows Media Device Manager. This parameter is optional and can be NULL. The context structure is a way for the component to send any relevant data with the event to the application. The component sending this structure should define how the application can interpret this data structure.

Return Values

Windows Media Device Manager ignores any return code returned by the End3 method because the current operation is finished or cancelled before this method is called.

Remarks

The interface that owns the method that is implementing an operation calls End3 when the operation defined by the method is completed.

Example Code

The following C++ code shows an example implementation of End3.

HRESULT End3(GUID  EventId, HRESULT  hrCompletionCode, OPAQUECOMMAND*  pContext)
{
    // TODO: Display the message "IWMDMProgress3::End3 called."
    return S_OK;
}

Requirements

Header: Defined in mswmdm.h.

Library: mssachlp.lib
