Prior to establishing an operating system dependent +signal handler the application may call +.ZN 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 +passing the \fIid\fP returned by the call to +.ZN XtAppAddSignal . +.LP +.ZN XtNoticeSignal +is the only Intrinsics function that can safely be called from a signal +handler. If +.ZN 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 +and is set to +.ZN True +by +.ZN XtNoticeSignal ; +the Intrinsics invoke the callback whenever the flag is +.ZN True , +and the flag is set to +.ZN False +just before the callback is invoked. +.LP +The +.ZN XtRemoveSignal +function is called to remove the specified Intrinsics signal handler. The +client should disable the source of the signal before calling +.ZN XtRemoveSignal . +.SH "SEE ALSO" +XtAppAddTimeOut(3Xt),XtAppAddInput(3Xt),XtAppAddWorkProc(3Xt) +.br +\fI\*(xT\fP +.br +\fI\*(xL\fP |
