Yes, you can have multiple readers of a socket. But the results will be unpredictable. Especially if it's a SOCK_STREAM (e.g., TCP) socket. You should only do that if it's a SOCK_DGRAM (e.g., UDP) socket but even then you won't be able to predict which goroutine reads a particular packet. Note that this doesn't really have anything to do with Go. It's just how network sockets work and the answer is the same if the language was C/C++. Your question is equivalent to asking if you can have multiple goroutines reading from the same file descriptor opened on a pipe. The answer is, yes, but as with sockets you'll get unpredictable results. -- Kurtis Rader Caretaker of the exceptional canines Junior and Hank -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
