IWMSCacheProxy::CreateCacheItemCollection

The CreateCacheItemCollection method is called by the server to create an IWMSCacheItemCollection interface and retrieve a pointer to it.

Syntax

  HRESULT CreateCacheItemCollection(
  
  IWMSCacheItemCollection**
  
  ppCacheItemCollection
  
  );

Parameters

ppCacheItemCollection

[out] Pointer to pointer to an IWMSCacheItemCollection interface.

Return Values

If the method succeeds, the plug-in must return S_OK. To report an error, the plug-in can return any HRESULT other than S_OK. If the plug-in uses the IWMSEventLog interface to log error information directly to the Windows Event Viewer, it is recommended that it return NS_E_PLUGIN_ERROR_REPORTED. Typically, the server attempts to make plug-in error information available to the server object model, the Windows Event Viewer, and the troubleshooting list in the details pane of the Windows Media Services MMC. However, if the plug-in uses the IWMSEventLog interface to send custom error information to the Windows Event Viewer, returning NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about retrieving plug-in error information, see Identifying Plug-in Errors.

Remarks

The IWMSCacheItemCollection interface contains a collection of IWMSCacheItemDescriptor interfaces. The IWMSCacheItemDescriptor interface retrieves the size, version number, expiration date, and URL of cached content.

      if (FAILED(hr)) goto EXIT;

    // TODO: Release temporary objects.
