I know this topic is a bit old, but I needed it recently on Windows and
I'll post here how I did it in case someone else needs.
I used Windows mutex as described by ankurg...@gmail.com:
var (
kernel32 = syscall.NewLazyDLL("kernel32.dll")
procCreateMutex = kernel32.NewProc("CreateMutexW")
)
func CreateMutex(name string) (uintptr, error) {
ret, _, err := procCreateMutex.Call(
0,
0,
uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr(name))),
)
switch int(err.(syscall.Errno)) {
case 0:
return ret, nil
default:
return ret, err
}
}
// mutexName starting with "Global\" will work across all user sessions
_, err := CreateMutex("SomeMutexName")
I created a lib with a more complete example:

Thx!
