I found your program that uses the alarm clock to time how long before gethostbyaddr gets carried away forever. I did not know how to answer on the internet.
Does the program work? It ends the program itself, but do you know how to end the search? I have a file of about 300 ip addresses that I need to get the host names for, but I don't want to bail out of the program, just out of the gethostbyaddr function call so that it does not hang forever on one ip address, but goes to the next.
