Otherwise: A call to xname returns the connection number of the display specified by the .A display argument. >>STRATEGY If the system is POSIX compliant: Open a display using XOpenDisplay. Create a child process. In Child : Set IOErrorHandler to an errorhandler function which exits immediately. Obtain the connection number of the display using xname. Close the connection using close. Perform a XNoOp request on the display. Flush the O/P using using XFlush. In parent: Obtain child's exit status. Verify that the child exited from the error handler.
