CreateProcess such that child process is killed when parent is killed?

Question

Is there a way to call CreateProcess such that killing the parent process automatically kills the child process?

Perhaps using Create Process Flags?

Do you need the child process to be killed, or merely detect the parent process exit so it can terminate cleanly? The parent process can create an inheritable handle to itself, which the child can then pass to WaitForMultipleObjects(Ex) along with its own objects.

If the child process isn't written specifically for this, you could attach its stdin to a pipe, the other end of which is held by the parent process. If the parent dies, the pipe is automatically closed.

This closely parallels the Unix behavior, in which a child isn't killed when its parent dies, it generally exits in response to SIGHUP (but it can handle that signal and implement any behavior). On Linux, the parent PID of an orphan is changed to 1 (init).
