Hello, There are two questions. I am studying the book of Network Security with OpenSSL. In the source code listed, it refers to one function called "check_availability" but I cannot find the source of it. If you happen to have it, could you please let me know? Thank you for the help. While I am trying to implement "check_availability" myself, I use "select()" but sometimes it returns errno of EINTR. In such case, what shall I do? I don't know how to handle it properly. Is it risky to keep trying? Thanks again. Regards, Igenyar -------------- next part -------------- An HTML attachment was scrubbed...
