func CommandCombinedOutput ¶

func CommandCombinedOutput(cmd *exec.Cmd) ([]byte, error)

CommandCombinedOutput is like cmd.CombinedOutput, but for use when the reaper is running.

func Start ¶

func Start() error

Start starts the child process reaper.

func StartCommand ¶

func StartCommand(cmd *exec.Cmd) error

StartCommand starts the command and registers its PID with the reaper.

After the reaper has been started, users of os/exec should call WaitCommand and StartCommand rather than cmd.Wait directly, to ensure PIDs are reaped correctly.

func Stop ¶

func Stop() error

Stop stops the child process reaper.

func WaitCommand ¶

func WaitCommand(cmd *exec.Cmd) (int, error)

WaitCommand waits for the command (which must have been started with StartCommand) to finish and returns its exit code. Unlike cmd.Wait, WaitCommand doesn't return an error for nonzero exit codes.
