DESCRIPTION
The XtAppAddSignalHandler function initiates a mechanism for handling
signals within the context of the Intrinsics. Prior to establishing an
operating system dependent signal handler the application may call
XtAppAddSignalHandler and store the returned id in a place accessible
to the signal handler.
Upon receipt of a signal from the operating system, the application may
call XtNoticeSignal passing the id returned by the call to XtAppAddSigâ
nal.
