if it does not exist, does it return immediately or does it use the timeout?

winio returns immediately with a file not found error because the \\.\pipe\whatever does not yet exist.

@crosbymichael - Hang on this is the wrong commit. I dont quite know what happened but this doesnt have the right exit logic it it connects successfully.

I mean if you are still working on it, you could maybe use a:

select {
case <-time.After(timeout):
case <-pipe:
...
}

as a way to synchronize

Ok this is now right.

I can do it that way if you prefer. Doesn't bother me either way. Since winio returns immediately for file not found it would still require the same looping logic and starting a new select query so it seems the same code in the end.

This is now unreachable

That's a great point. Missed that case will submit a fix.
