Send signal *sig* to the process *pid*. Constants for the specific signals
available on the host platform are defined in the :mod:`signal` module.
- Availability: Unix.

+ Windows: The :data:`signal.CTRL_C_EVENT` and
+ :data:`signal.CTRL_BREAK_EVENT` signals are special signals which can
+ only be sent to console processes which share a common console window,
+ e.g., some subprocesses. Any other value for *sig* will cause the process
+ to be unconditionally killed by the TerminateProcess API, and the exit code
+ will be set to *sig*. The Windows version of :func:`kill` additionally takes
+ process handles to be killed.
