UDP and select() confusion


Somewhere here I am not thinking straight :

I can't use select() in a connectionless situation, that is, where I am using recvfrom() and sendto(), at least not in a way that does any good

If I use connected datagram sockets the first client to connect() will hog the server since the server's fd is "taken"

So, what to do ? Use non-blocking sockets and a timer ?

The site is a good socket reference:

Select can be used.

Here's where my thinking was flawed, I thought that recvfrom() specified exactly from who you will recieve !! Lo and behold, it just pulls in a packet then tells you who it's from so that is much easier. Problem solved.
