The IWMSServer interface resides at the top of the server hierarchy. You can use it to specify and retrieve server properties, and to create objects needed to manage a server.

In addition to the methods inherited from IDispatch, the IWMSServer interface exposes the following methods.

Method	Description

DownloadContent	Downloads audio or video content locally using the WMS Archive Data Writer plug-in.
ExportXML	Creates an XML document containing the server configuration data.
get_AllowClientsToConnect	Retrieves a Boolean value that indicates whether the server can receive client connections.
get_Authenticators	Retrieves an IWMSPluginsIWMSPlugins Interface containing a collection of authentication plug-ins. You can use authentication plug-ins to establish the identity of clients that are requesting connections.
get_AvailableIPAddresses	Retrieves an IWMSAvailableIPAddressesIWMSAvailableIPAddresses Interface containing a collection of IP addresses that can be used by the server to publish content.
get_CacheProxy	Retrieves an IWMSPlugins interface containing a collection of cache plug-ins that can be used to control the caching policy of the server.

get_StartTime	Retrieves the date and time at which the Windows Media server was started.
get_Status	Retrieves an enumeration value indicating the current state of the server.
get_StreamFilters	Reserved for future use.
get_TotalCounters	Retrieves an IWMSServerTotalCountersIWMSServerTotalCounters Interface that can be used to obtain information about various totals maintained by the server.
get_UnicastDataSinks	Retrieves an IWMSPlugins interface containing a collection of unicast data sink plug-ins that can be used to send data packets to a client.

Example

The following example illustrates how to retrieve a pointer to an IWMSServer interface.

#include <windows.h>
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer      *pServer;
HRESULT         hr;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
                      NULL,
                      CLSCTX_ALL,
                      IID_IWMSServer,
                      (void **)&pServer);
if (FAILED(hr)) goto EXIT;

EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.
