ue4 socket

Socket 地址：

TSharedRef<FInternetAddr> internetAddr = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateInternetAddr();
bool bIsValid = true;
internetAddr->SetIp(*serverIp, bIsValid);
internetAddr->SetPort(serverPort);

socket tcp连接

connect send closeConnect

mySocket = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateSocket(EName(NAME_Stream), "TCP Server");
if (mySocket->Connect(internetAddr.Get()))

udp协议下

sendTo(address,data)

udpSocket = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateSocket(EName(NAME_DGram), "UDP Client");
udpSocket->SendTo(buffer, 4, bytesSend, internetAddr.Get());

接收

int32 recvProgress;
uint8 recvBuffer[BUFFER_SIZE];
mySocket->Recv(recvBuffer, sizeof(uint8) * msgLen, recvProgress, ESocketReceiveFlags::None);
ESocketReceiveFlags::Peek

标志和windows socket有很多通用的地方： 如waitall peek none
udp socket 接收方需要绑定ip  发送方不需要。
waitall 不能用在datagram 也就是UDP上 可参考MSDN。UE文档关于waitall的备注也有写。
