Is it possible to capture a Ctrl+C signal and run a cleanup function, in a “defer” fashion?

Question

I want to capture the Ctrl+C (SIGINT) signal sent from the console and print out some partial run totals.

Is this possible in Golang?

Answer 1

Just for the record if somebody needs a way to handle signals on Windows. I had a requirement to handle from prog A calling prog B through os/exec but prog B never was able to terminate gracefully because sending signals through ex. cmd.Process.Signal(syscall.SIGTERM) or other signals are not supported on Windows. The way I handled is by creating a temp file as a signal ex. .signal.term through prog A and prog B needs to check if that file exists on interval base, if file exists it will exit the program and handle a cleanup if needed, I'm sure there are other ways but this did the job.
