func Trap ¶

func Trap(cleanup func())

Trap sets up a simplified signal "trap", appropriate for common behavior expected from a vanilla unix command-line tool in general (and the Docker engine in particular).

The first time a SIGINT or SIGTERM signal is received, `cleanup` is called in a new goroutine.

If SIGINT or SIGTERM are received 3 times, the process is terminated immediately with an exit code of 128 + the signal number.
