Here's what the standard says about the backlog parameter:
"The backlog argument provides a hint to the implementation which the
implementation shall use to limit the number of outstanding connections in
the socket's listen queue."
To us, this always meant that the backlog is the number of connections that are
accepted internally (SYN-ACK sent) and not yet received by the application code
(using accept()).
What you want (number of connections to one port) is a different thing. You'd
have to implement it manually by either closing the listening port and
reopening it later or by closing all new connections when your maximum number
of parallel connections is reached.
