Hi,
I have a code snippet background. It will check if a given process is
exited. But based on my test, the first line syscall.Kill will always
return nil even if the child process is already done (e.g. In the test, I
ran an 'echo' command first and sleep for a long time before calling the
code snippet above).
I use cmd.Start to start my child process.
Anyone knows why?
Thanks,
Yihao
