38 * This program creates a socket in the UNIX domain and binds a name to it.
39 * After printing the socket's name it begins a loop. Each time through the
40 * loop it accepts a connection and prints out messages from it. When the
41 * connection breaks, or a termination message comes through, the program
42 * accepts a new connection.

82 * The following statements are not executed, because they follow an
83 * infinite loop. However, most ordinary programs will not run
84 * forever. In the UNIX domain it is necessary to tell the file
85 * system that one is through using NAME. In most programs one uses
86 * the call unlink() as below. Since the user will have to kill this
87 * program, it will be necessary to remove the name by a command from
