Detailed Description
Global signal handling.
It is recommended to call the setDefaults method only, as this sets default signal handlers. The application may examine the global variables to find out whether a signal has been delivered.

Registers the built-in signal handler for the most important signals.
On the Win32 platform this also registers the calling thread as receiver for a WM_QUIT message. The signal handler sends this message whenever it catches a signal. Use setThreadMsg() to inhibit message sending or to set a different message to send.
