[ale] RE: listen()

[Joe Steele]

As I recall, you wanted to process only one 
connection at a time, rejecting additional connection 
requests until the current connection was closed.

You probably need to do something like this:

do
{
	sock1 = socket (...);
	bind (sock1,...);
	listen (sock1, 1);
	sock2 = accept (sock1,...);

	/* stop listening for other connection attempts */
	close (sock1); 
	
	/* Service the connection on sock2 */
	.
	.
	.
	/* terminate the connection */
	close (sock2);

	/* loop back and listen for another connection */
} while (continue_listening);

I have deleted my emails but a few weeks ago someone mentioned that I
should do an accept() instead of listen() -> accept() to get only one
connection. I tried that.

>>From accept(2);

The argument s is a socket that has been created with socket(2), bound
to a local address  with  bind(2), and is listening for connections
after a listen(2).

Maybe this trick works in BSD but not in Linux.  accept() gave me an
immediate error.
