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 XtAppAddSig‐
		 nal 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
       pending 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.
