Types ¶

type Signaler ¶

type Signaler interface {
	// Send uses the kill syscall to issue a given signal.
	Send(signal string) error
}

A Signaler is used to issue a signal to a process group.

func Signals ¶

func Signals(pid int) Signaler

Signals returns a Signaler that issues real os signals.

type WaitCh ¶

type WaitCh chan *drivers.ExitResult

type Waiter ¶

type Waiter interface {
	Wait() WaitCh
}

func WaitPID ¶

func WaitPID(pid int, taskdir string) Waiter

WaitPID is able to wait on a given specific PID. We must lookup the process and also send a signal(0) to make sure it is actually still alive before waiting on it.

func WaitProc ¶

func WaitProc(p *os.Process) Waiter

WaitProc makes use of the os.Process handle to wait on the child process. This is the handle returned from directly launching the process through the exec package.
