UDP Write() will not send 0 byte datagram #274
Description
by jonathan.r.hudson:
What steps will reproduce the problem?
1. Create a UDP socket
2. send a 0 byte datagram
var b [1]byte;
conn,err := net.DialUDP("udp", nil, raddr);
...
conn.Write(b[0:0]);
/* conn.WriteToUDP(b[0:0],raddr); // This works */
What is the expected output? What do you see instead?
It is expected that a 0 byte datagram is sent.
The 0 byte datagram is not sent. note: WriteToUDP works posixally correctly
(in this case a 0 byte datagram is sent).
What is your $GOOS? $GOARCH?
linux, amd64
