IWMSAdminUnicastSink::put_MinClientPacketSize
The put_MinClientPacketSize method specifies the minimum value of the packet size that a client can request.
Syntax
HRESULT put_MinClientPacketSize( long lMinClientMtu );
Parameters
lMinClientMtu
[in] long containing the minimum packet size.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Remarks
This property can be used to specify the minimum value that you can set when calling the IWMSAdminUnicastSink.put_MaximumPacketSize method. The maximum packet size that can be sent is 65,535 bytes. The minimum is 100 bytes. A value of zero indicates that the default size in the file is used.
Example Code
#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; long lMinPacketSize; // 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; // Specify the minimum packet size that can be requested // by a client. lMinPacketSize = 512; hr = pAdminUnicastSink->put_MinClientPacketSize(lMinPacketSize); if (FAILED(hr)) goto EXIT; EXIT: // Release temporary COM objects and uninitialize COM.
