IWMSBroadcastPublishingPoint::StopArchive

The StopArchive method stops archiving the content that was streamed by the publishing point.

Syntax

  HRESULT StopArchive( );

Parameters

This method takes no parameters.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code Number Description
NS_E_PUBLISHING_POINT_REMOVED 0xC00D145AL The publishing point has already been removed.

Remarks

The StopArchive method only stops the archiving process. If the broadcast publishing point is running, it will continue streaming content to the clients.

Example Code

#include <windows.h>
#include <atlbase.h>    // Includes CComVariant.
#include "wmsserver.h"

// Declare variables and interfaces.

        {
            hr = pBCPubPoint->StopArchive();
            if (FAILED(hr)) goto EXIT;
        } else
            hr = pBCPubPoint->StartArchive();
            if (FAILED(hr)) goto EXIT;
        }
        pBCPubPoint->Release();
    }
