But it is possible: https://play.golang.org/p/GhdrMkiElc. Another approach is to make the stdin file descriptor non-blocking, so that attempting to read from it will fail immediately if there is no data available. See: https://play.golang.org/p/yHrDdzWoDk Admittedly, neither of these approaches is straightforward. A more typical Go approach is to start the read in its own goroutine and let it run to completion, even if no data ever arrives. Of course, while simple to program, this is not ideal if you need to cancel the read after the timeout has expired. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
