有谁知道 WSAIoctl 的SIO_SET_QOS 如何控制 socket的流量的嘛?

[ctestcode]

QOS MyQos;

MyQos.SendingFlowspec.DelayVariation=2000;
MyQos.SendingFlowspec.Latency=2000;
MyQos.SendingFlowspec.MaxSduSize=8192;
MyQos.SendingFlowspec.MinimumPolicedSize=0;
MyQos.SendingFlowspec.PeakBandwidth=8192;
MyQos.SendingFlowspec.ServiceType=SERVICETYPE_BESTEFFORT;
MyQos.SendingFlowspec.TokenBucketSize=4096;
MyQos.SendingFlowspec.TokenRate=8192;

MyQos.ReceivingFlowspec.DelayVariation=2000;
MyQos.ReceivingFlowspec.Latency=2000;
MyQos.ReceivingFlowspec.MaxSduSize=8192;
MyQos.ReceivingFlowspec.MinimumPolicedSize=0;
MyQos.ReceivingFlowspec.PeakBandwidth=8192;
MyQos.ReceivingFlowspec.ServiceType=SERVICETYPE_BESTEFFORT;
MyQos.ReceivingFlowspec.TokenBucketSize=4096;
MyQos.ReceivingFlowspec.TokenRate=8192;

MyQos.ProviderSpecific.buf=NULL;
MyQos.ProviderSpecific.len=0;
nRet= WSAIoctl(socket, SIO_SET_QOS, (LPVOID)&MyQos, cbQosLen,NULL, 0,&dwBytes, NULL, NULL);
if (SOCKET_ERROR == nRet)
{
return 0;
}
我这样写 没有起作用,不知道为什么

// Implement send-side functionality. The sender uses a combination of

// WSASend and WSAEventSelect to support sending of either TCP or UDP data

// and receive notification of QOS activity on the socket.
