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...
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...
