修改socket缓存

c++：

//设置socket发送、接收缓冲区大小为64k，默认为8k，最大为64k

int value=65535;

int tmpCode=0;

tmpCode=::setsockopt(m_UdpSendSocket_Quot, SOL_SOCKET, SO_RCVBUF, (char*)&value, sizeof(value));

tmpCode=::setsockopt(m_UdpSendSocket_Quot, SOL_SOCKET, SO_SNDBUF, (char*)&value, sizeof(value));

int result=0;

int len=4;

tmpCode=::getsockopt((SOCKET)m_UdpSendSocket_Quot,SOL_SOCKET, SO_RCVBUF, (char*)&result, &len);

printf("SO_RCVBUF=%d, tmpCode=%d\n", result,tmpCode);

tmpCode=::getsockopt((SOCKET)m_UdpSendSocket_Quot,SOL_SOCKET, SO_SNDBUF, (char*)&result, &len);

printf("SO_SNDBUF=%d, tmpCode=%d\n", result,tmpCode);
