socket pair = client socket + server socket。 所以,当使用一个监听器监听时,一旦accept到一个connect后,可以,将这个socket交给一个线程或进程执行任务,在线程中执行这个任务的同时,主线程仍然可以accept其他client socket的链接。因为,每个tcp connection的socket pair中的client socket是不一样的,所以tcp是可以区分...
10~11 socket函数创建一个网际(AF_INET)字节流(SOCK_STREAM)套接字,它是TCP套接字的花哨名字。该函数返回一个小整数描述符,以后的所有函数调用(如随后的connect和read)就用该描述符来标识这个套接字。 7 if语句包含3个操作:调用socket函数,把返回值赋给变量sockfd,再测试所赋的这个值是否小于0。虽然我们可以...
Why oh why does executing from php a script under sudo as apache cause supervisorctl not to be able to open the UNIX domain socket that is clearly sitting in /tmp and listening? EDIT: EL6 seems to work with zero code changes. But EL7 fails. The only difference I can think of is pyt...
In addition to sending data, processes may send file descriptors across a Unix domain socket connection using the sendmsg() and recvmsg() system calls. This allows the sending processes to grant the receiving process access to a file descriptor for wh...

Close the connection: You can close the connection either by calling close(), or by calling shutdown(). With all that said, here is some source for an echoing server, echos.c. All it does is wait for a connection on a Unix socket (named, in this case, "echo_socket"). ...
