怎么查看网络流量

Question

我想知道上网的流量，不知道有什么api函数之类，还是有什么其他的方法，

Answer 1

void CTrafficMonitorInfo::NetworkTraffic()
{
DWORD             dwIndex;
DWORD             dwResult;
ULONG             OutBufLen;
IP_ADAPTER_INFO   AdapterInfo;
   PIP_ADAPTER_INFO  pAdapterNext;
MIB_IFROW         IfRow; OutBufLen = sizeof(IP_ADAPTER_INFO);
dwResult  = GetAdaptersInfo(&AdapterInfo,&OutBufLen);
if(dwResult == ERROR_BUFFER_OVERFLOW)
{
GetAdaptersInfo(&AdapterInfo,&OutBufLen);
}
else if (dwResult != ERROR_SUCCESS)
{
printf("GetAdaptersInfo Error: %d\n",GetLastError());
} pAdapterNext = &AdapterInfo;
while(pAdapterNext != NULL)
{
dwIndex = pAdapterNext->Index; IfRow.dwIndex = dwIndex;
if((dwResult  = GetIfEntry(&IfRow)) != NO_ERROR)
{
printf("GetIfEntry Error: %d\n",dwResult);
break;
} printf("\t%12s%12s%10s\t%s\n","Unicast","NUnicast","Error","Bytes");
printf("%s\t%12d%12d%10d\t%d\n","Send:",IfRow.dwOutUcastPkts,IfRow.dwOutNUcastPkts,IfRow.dwOutErrors,IfRow.dwOutOctets);
printf("%s%12d%12d%10d\t%d\n","Receive:",IfRow.dwInUcastPkts,IfRow.dwInNUcastPkts,IfRow.dwInErrors,IfRow.dwInOctets);
printf("%s\t%12d%12d%10d\t%d\n","Total:",
   IfRow.dwInUcastPkts  + IfRow.dwOutUcastPkts,
   IfRow.dwInNUcastPkts + IfRow.dwOutNUcastPkts,
   IfRow.dwInErrors     + IfRow.dwOutErrors,
   IfRow.dwInOctets     + IfRow.dwOutOctets);
}
稍微改一下，放定时器里面就可以了。
