以下是 TCP Socket 写操作性能优化的最佳实践示例: 批量发送数据: 使用writev 或 sendv 函数进行批量发送多个缓冲区的数据。 struct iovec iov[2]; char *message1 = "Hello,"; char *message2 = " world!"; iov[0].iov_base = message1; iov[0].iov_len = strlen(message1); iov[1].iov_base =...
SocketClient so = SocketClient("192.168.0.179"); so.sendTo("Hello from C++ 111"); so.sendTo("Hello from C++ 222"); so.~SocketClient();/*WSAData data; SOCKET sock; struct sockaddr_in si_other; const std::string address = "192.168.0.179"; int slen = sizeof(si_other); char messa...
ServerClientServerClient创建Socket连接到服务器发送数据: "Hello, Server!"确认收到 如何使用flags参数 在实际使用中,您可以根据需求选择合适的flags参数。例如,如果您想避免因写入已关闭的Socket而导致的崩溃,可以使用MSG_NOSIGNAL标志。 send(sockfd,message,strlen(message),MSG_NOSIGNAL); 1. 这将确保在发生Socket...
send是TCP通信的发送方法，在send之前保证建立了socket通信连接，socket中记录了与之连接的对方的地址，所以可以说是第一个参数SOCKET记录了要发往的地址；注：TCP套接字只能进行一对一的通信，所以不需要地址再来进行目的地的标识，套接字就可以确定要发往的方向；SOCKET Sock；Sock=socket（AF_INET,SOCK...
