XtNoticeSignal(3X)						   XT FUNCTIONS 						XtNoticeSignal(3X)

NAME
       XtNoticeSignal - register and remove a signal source

SYNTAX
       void XtNoticeSignal(id)
	     XtSignalId id)

ARGUMENTS
       id	 Specifies the ID returned from the corresponding XtAppAddSignal call.

DESCRIPTION
       XtNoticeSignal is the only Intrinsics function that can safely be called from a signal handler. If XtNoticeSignal is called multiple times
       before the Intrinsics are able to invoke the registered callback, the callback is only called once. Logically the Intrinsics maintain pend-
       ing for each registered callback. This flag is initially False and is set to True by XtNoticeSignal; the Intrinsics invoke the callback
       whenever the flag is True, and the flag is set to False just before the callback is invoked.
