The attempted operation is not supported for the type of object referenced. Usually this occurs when a socket descriptor to a socket that cannot support this operation, for example, trying to accept a connection on a datagram socket.

int accept(int sockfd, struct sockaddr *addr, socklen_t *addrlen); 参数说明sockfd是由socket函数返回的套接字描述符,参数addr和addrlen用来返回已连接的对端进程(客户端)的协议地址。如果我们对客户端的协议地址不感兴趣,可以把arrd和addrlen均置为空指针。 返回值 成功时,返回非负整数,该整数是接收到套...
Socket Accept timeout: This is an important yet overlooked scenario. Sometimes when you try to open a socket, you may not get any response from the other end. Due to this, you are left waiting forever. This is an unwanted situation as you would like to close the current request and try...
服务器端先初始化Socket,然后与端口绑定(bind),对端口进行监听(listen),调用accept阻塞,等待客户端连接。在这时如果有个客户端初始化一个Socket,然后连接服务器(connect),如果连接成功,这时客户端与服务器端的连接就建立了。客户端发送数据请求,服务器端接收请求并处理请求,然后把回应数据发送给客户端,客户端读取数据...
你调用accept的时候就是从这个接收队列中获取一个握手就绪连接来用。再后面就是在这个连接之上的读和写...
