How to solve Connect() time-out issues on blocking socket(for SSL handshake)?

This type of question is(with a lot of variations) kinda answered but.. I do need a blocking connect(i'm using SSL)on a socket, that i can set a time-out and maximum number of retries and all that is necessary for never lasting more than t seconds.

I just hope there is some thing i can set in the OS(linux: Ubuntu/CentOS) or some way to do this in code(C) w/o going for an ugly, artificial way like select wait, timeout events added to epoll that close the socket. thank you.

The simplest way to do this is to use alarm system call before and after a connect call and to handle Alarm signal, but this is not the best and most useful way. The better and recommended way is to use a non-blocking socket and use poll or select system calls to handle different stages of making a connection. But if you don't want to use Non-blocking IO your only way is to use alarm.

For a tutorial about using non-blocking sockets refer to : http://developerweb.net/viewtopic.php?id=3196

For more information about what happens during a connect call refer to: http://www.madore.org/~david/computers/connect-intr.html
