### Minimal windows service stub |
|
||||||
|
|
||||||
Programs designed to run from most *nix style operating systems |
|
||||||
can import this package to enable running programs as services without modifying |
|
||||||
them. |
|
||||||
|
|
||||||
``` |
|
||||||
import _ "github.com/kardianos/minwinsvc" |
|
||||||
``` |
|
||||||
|
|
||||||
If you need more control over the exit behavior, set |
|
||||||
``` |
|
||||||
minwinsvc.SetOnExit(func() { |
|
||||||
// Do something. |
|
||||||
// Within 10 seconds call: |
|
||||||
os.Exit(0) |
|
||||||
}) |
|
||||||
``` |
