IWMSAuthenticationContext::GetAuthenticationPlugin
The server calls the GetAuthenticationPlugin method to retrieve a pointer to the authentication plug-in.
Syntax
HRESULT GetAuthenticationPlugin( IWMSAuthenticationPlugin** ppAuthenPlugin );
Parameters
ppAuthenPlugin
[out] Pointer to a pointer to an IWMSAuthenticationPlugin 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.
Example Code
HRESULT CAuthentContext::GetAuthenticationPlugin( IWMSAuthenticationPlugin **ppAuthenPlugin ) { // Call QueryInterface and return the pointer. return pAuthPlug->QueryInterface(IID_IWMSAuthenticationPlugin, (void**) ppAuthenPlugin); }
