What is usually done is to use non-blocking connect(2) (see fcntl(2) and O_NONBLOCK), and then do a select(2) with a timeout to wait for this connect to finish (or close(2) on timeout). I suggest you take a look at Stevens' UNIX Network Programming for more information about this and other techniques (it's a big book, and contains many useful tips and techniques for socket programming in Unix). I don't know if a free quality alternative exists online. -- Nadav Har'El | Sunday, Apr 7 2002, 25 Nisan 5762 [EMAIL PROTECTED] |----------------------------------------- Phone: +972-53-245868, ICQ 13349191 |I put a dollar in one of those change http://nadav.harel.org.il |machines.
