>>ASSERTION Good D 1
If the system is POSIX compliant:
A call to xname returns the file descriptor of the display
specified by the
.A display
argument.
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.
Otherwise:
UNTESTED
