UDP Socket Read Question

Alkaline

I've been trying to find this on the net through constant googling but
I can't. Does a read() call (or any receive call for that matter) on a
udp socket read at most 1 udp packet or will it read potentially
several? Anyone know where to find documentation on this?

Thank you.

It will read at most 1 packet. I expect this is mentioned somewhere in
Unix Network Programming -- if you're doing any significant amount of
socket programming, you really should have this book.
