Defines 14 Classes
Extends 7 Classes

OSProcessSignalHandler handles OS signals (interrupt/terminate etc) sent to VisualWorks, and announces them to interested parties.

The announcements must be subscribed after each image startup.

OS specific notes:
- On Windows, both console events (Ctrl-C etc.) and events sent to application windows and unknown to the VM are handled.
Note that CTRL_LOGOFF_EVENT and CTRL_SHUTDOWN_EVENT are only passed to services. Consider using the package WinService.
- On Unix, Unix signals are announced. No power events (hibernate etc.) are announced.
- On OS X, power events and Unix signals are announced.

Example:

OSProcessSignalHandler current
when: OSProcessSignal do: [ : signal | Transcript show: signal signalName; cr ];
when: OSProcessCloseSignal do: [ : signal | Transcript show: 'Bye bye'; cr. ObjectMemory quit ];
