+  Just like \ex{connect-socket}, \ex{connect-socket-no-wait} sets up a
+  connection from a \var{socket} to a remote \var{socket-address}.
+  Unlike \ex{connect-socket}, \ex{connect-socket-no-wait} does not
+  block if it cannot establish the connection immediately. Instead it
+  will return \sharpf{} at once. In this case a subsequent \ex{select} on
+  the output port of the socket will report the output port as ready
+  as soon as the operation system has established the connection or as
+  soon as setting up the connection led to an error. Afterwards, the
+  procedure \ex{connect-socket-successful?} can be used to test
+  whether the connection has been established successfully or not.
