Socket设置超时有问题？？？？

[dulei115]

//SetSocketTimeOut的的声明：
static bool SetSocketTimeOut(SOCKET Con, int MilliSeconds = 30000, int Type = 2);
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
//SetSocketTimeOut的的定义：
{
struct timeval tm;
tm.tv_sec = MilliSeconds / 1000;
tm.tv_usec = MilliSeconds % 1000 * 1000;
if (Type == 0)
return setsockopt(Con, SOL_SOCKET, SO_SNDTIMEO, (char *)&tm, sizeof(tm)) == 0;
else if (Type == 1)
return setsockopt(Con, SOL_SOCKET, SO_RCVTIMEO, (char *)&tm, sizeof(tm)) == 0;
else
return (setsockopt(Con, SOL_SOCKET, SO_SNDTIMEO, (char *)&tm, sizeof(tm)) == 0)
&& (setsockopt(Con, SOL_SOCKET, SO_RCVTIMEO, (char *)&tm, sizeof(tm)) == 0);
//下面这个也有试过，效果一样
//if(Type == 0)
// return setsockopt(Con, SOL_SOCKET, SO_SNDTIMEO, (char *)&MilliSeconds, sizeof(MilliSeconds)) == 0;
//else if (Type == 1)
// return setsockopt(Con, SOL_SOCKET, SO_RCVTIMEO, (char *)&MilliSeconds, sizeof(MilliSeconds)) == 0;
//else
// return (setsockopt(Con, SOL_SOCKET, SO_SNDTIMEO, (char *)&MilliSeconds, sizeof(MilliSeconds)) == 0)
// && (setsockopt(Con, SOL_SOCKET, SO_RCVTIMEO, (char *)&MilliSeconds, sizeof(MilliSeconds)) == 0);
}
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
//部分代码，中间都有加错误处理
cntaddr_in.sin_family = AF_INET;
cntaddr_in.sin_addr.s_addr=inet_addr(vIP);
cntaddr_in.sin_port = ntohs(vPort);
m_connectfd = socket(AF_INET, SOCK_STREAM, 0);
MyClass::SetSocketTimeOut(m_connectfd);
connect(m_connectfd, (struct sockaddr *)&cntaddr_in, sizeof(struct sockaddr_in);
send(m_connectfd,(char *)send_buf,send_len,0);
recv_len=recv(m_connectfd,(char *)recv_buf,sizeof(recv_buf),0);
------------------------------------------------------------------------------------
结果是不管服务端有没有返回，recv马上就返回结果了，recv_len始终是返回0，紧接着WSAGetLastError()的结果是10060 Connection timed out，而服务端显示10054 Connection reset by peer，表示我这边断开了。去掉设置超时的代码就没事了，但是我一定要设置超时的，因为服务端有可能会没有响应。请问各位，我这段代码哪里有问题？？？

我有判断返回值的，只是没有写出来，我试试用两个变量的。

int iSendTime = 5000;//5秒
int iRecvTime = 5000;
setsockopt(Consock, SOL_SOCKET, SO_SNDTIMEO, (const char*)&iSendTime, sizeof(iSendTime));
setsockopt(Consock, SOL_SOCKET, SO_RCVTIMEO, (const char*)&iRecvTime, sizeof(iRecvTime));

setsockopt要判断返回值，是否设置成功
