You might not have to use alarm. I think you can make the connection non-blocking, then detect when the connection is completed using select. select accepts a timeout, which would replace your use of alarm.

If that works, the advatage is you can extend that model to initiate connections to more than one address at a time, and work with the connections as they become available. This is particularly useful if you expect a lot of timeouts.
