+otherwise, they should call +.ZN XtDestroyApplicationContext +or just exit. +.LP +The +.ZN XtDatabase +function returns the fully merged resource database that was built by +.ZN XtDisplayInitialize +associated with the display that was passed in. +If this display has not been initialized by +.ZN XtDisplayInitialize , +the results are not defined. +.LP +The +.ZN XtScreenDatabase +function returns the fully merged resource database associated with the +specified screen. If the \fIscreen\fP does not belong to a +.ZN Display +initilized by +.ZN XtDisplayInitialize , +the results are undefined. +.SH "SEE ALSO" +XtAppCreateShell(3Xt), +XtCreateApplicationContext(3Xt) +.br +\fI\*(xT\fP +.br +\fI\*(xL\fP |
