and independent from options or which
function was used to start the
killSignal :: Signal -> UnsafeChildProcess -> Effect Boolean
Send a signal to a child process. In the same way as the unix kill(2) system call, sending a signal to a child process won't necessarily kill it.
The resulting effects of this function depend on the process
and the signal. They can vary from system to system.
The child process might emit an
"error" event if the signal
could not be delivered.
