+ *  Sends the given signal to the specified process id(s), or to the
+ *  current process if _pid_ is zero. _signal_ may be an
+ *  integer signal number or a POSIX signal name (either with or without
+ *  a +SIG+ prefix). If _signal_ is negative (or starts
+ *  with a minus sign), kills process groups instead of
+ *  processes. Not all signals are available on all platforms.
