Prior to establishing an operating system dependent signal handler the application may call -.ZN XtAppAddSignal +.BR XtAppAddSignal and store the returned \fIid\fP in a place accessible to the signal handler. .LP Upon receipt of a signal from the operating system, the application may call -.ZN XtNoticeSignal +.BR XtNoticeSignal passing the \fIid\fP returned by the call to -.ZN XtAppAddSignal . +.BR XtAppAddSignal . .LP -.ZN XtNoticeSignal +.BR XtNoticeSignal is the only Intrinsics function that can safely be called from a signal handler. If -.ZN XtNoticeSignal +.BR 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 -.ZN False +.BR False and is set to -.ZN True +.BR True by -.ZN XtNoticeSignal ; +.BR XtNoticeSignal ; the Intrinsics invoke the callback whenever the flag is -.ZN True , +.BR True , and the flag is set to -.ZN False +.BR False just before the callback is invoked. .LP The -.ZN XtRemoveSignal +.BR XtRemoveSignal function is called to remove the specified Intrinsics signal handler. The client should disable the source of the signal before calling -.ZN XtRemoveSignal . +.BR XtRemoveSignal . .SH "SEE ALSO" XtAppAddTimeOut(__libmansuffix__),XtAppAddInput(__libmansuffix__),XtAppAddWorkProc(__libmansuffix__) .br |
