Kills the process.
Where possible, sends the signal to the process. This includes Linux and OS X. The default signal is ProcessSignal.SIGTERM which will normally terminate the process.
On platforms without signal support, including Windows, the call
just terminates the process in a platform specific way, and the
signal
parameter is ignored.
Returns true
if the signal is successfully delivered to the
process. Otherwise the signal could not be sent, usually meaning
that the process is already dead.
