3 years ago This works but I wonder if a simpler approach would just be to set
p.Interval = time.Nanosecond?
Sure, that works. That was in fact my first approach. It has the nasty side-effect of the ticker triggering as fast as it can and it keeps firing until all the packets have been received. This implementation does the same with a little less overhead and blocking that select interval case as soon as all the required packets have been sent out.
time.NewTicker doesn't like an interval of 0, but it's useful in order to send a "flood ping" (see for example https://www.freebsd.org/cgi/man.cgi?ping(8) or https://linux.die.net/man/8/ping). It would be up to the user of the library to limit the number of in-flight pings in the manner described in the manpages.
