示例1: setUDPRecvBuf
// setUDPRecvBuf is used to resize the UDP receive window. The function
// attempts to set the read buffer to `udpRecvBuf` but backs off until
// the read buffer can be set.
func setUDPRecvBuf(c *net.UDPConn) {
size := udpRecvBuf
for {
if err := c.SetReadBuffer(size); err == nil {
break
}
size = size / 2
}
}示例2: main
func main() {
listen := flag.String("addr", ":2055", "Listen address")
flag.Parse()
var addr *net.UDPAddr
var err error
if addr, err = net.ResolveUDPAddr("udp", *listen); err != nil {
log.Fatal(err)
}
var server *net.UDPConn
if server, err = net.ListenUDP("udp", addr); err != nil {
log.Fatal(err)
}
if err = server.SetReadBuffer(readSize); err != nil {
log.Fatal(err)
}
