IWMSAdminUnicastSink Interface
The IWMSAdminUnicastSink interface is a data sink that you can use to send content to unicast clients. It is exposed by the WMS Unicast Data Sink plug-in.
In addition to the methods inherited from IDispatch, the IWMSAdminUnicastSink interface exposes the following methods.
Method | Description |
get_DataProtocols | Retrieves a semicolon delimited list of the data protocols supported by the plug-in. |
get_DefaultPacketSize | Retrieves a Boolean value indicating whether the network packet size should default to the packet size of the content being delivered. |
get_MaximumPacketSize | Retrieves the maximum packet size that can be sent by the unicast data sink. |
get_MinClientPacketSize | Retrieves the minimum value of the packet size that a client can request. |
get_OptimalPacketSize | Retrieves the optimal packet size sent by the unicast data sink. |
get_TCPEnabled | Retrieves a Boolean value indicating whether the unicast data sink can use TCP when selecting a streaming protocol. |
get_ThirdPartyStreamingEnabled | Retrieves a Boolean value indicating whether UDP packets can be sent to an IP address that differs from the address of the client's TCP connection. |
get_UDPEnabled | Retrieves a Boolean value indicating whether the unicast data sink can use UDP when selecting a streaming protocol. |
put_DefaultPacketSize | Specifies a Boolean value indicating whether the network packet size should default to the packet size of the content being delivered. |
put_MaximumPacketSize | Specifies the maximum packet size that can be sent by the unicast data sink. |
put_MinClientPacketSize | Specifies the minimum value of the packet size that a client can request. |
put_OptimalPacketSize | Specifies the optimal packet size sent by the unicast data sink. |
put_TCPEnabled | Specifies a Boolean value indicating whether the unicast data sink can use TCP when selecting a streaming protocol. |
put_ThirdPartyStreamingEnabled | Specifies a Boolean value indicating whether UDP packets can be sent to an IP address that differs from the address of the client's TCP connection. |
put_UDPEnabled | Specifies a Boolean value indicating whether the unicast data sink can use UDP when selecting a streaming protocol. |
Example Code
The following example illustrates how to retrieve a pointer to an IWMSAdminUnicastSink interface.
#include <windows.h> #include <atlbase.h> // Includes CComVariant. // To access system plug-in interfaces, the // entire type library must be imported as shown. #import "WMSServerTypeLib.dll" no_namespace named_guids \ raw_interfaces_only // Declare variables and interfaces. IWMSServer *pServer; IWMSPlugins *pPlugins; IWMSPlugin *pPlugin; IDispatch *pDispatch; IWMSAdminUnicastSink *pAdminUnicastSink; HRESULT hr; CComVariant varIndex; // 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; // Retrieve a pointer to an IWMSPlugins interface // containing unicast data sink plug-ins. hr = pServer->get_UnicastDataSinks(&pPlugins); if (FAILED(hr)) goto EXIT; // Retrieve a pointer to the IWMSPlugin interface // of the plug-in to be configured. varIndex = "WMS Unicast Data Writer"; hr = pPlugins->get_Item(varIndex, &pPlugin); if (FAILED(hr)) goto EXIT; // Retrieve a pointer to the custom interface // of the plug-in. hr = pPlugin->get_CustomInterface(&pDispatch); if (FAILED(hr)) goto EXIT; // Query the specific administration interface // for the plug-in. hr = pDispatch->QueryInterface(IID_IWMSAdminUnicastSink, (void **)&pAdminUnicastSink); if (FAILED(hr)) goto EXIT; EXIT: // TODO: Release temporary COM objects and uninitialize COM.
