The string-to-backing-store converter in the Xmu library returns a backing store of Always+WhenMapped+NotUseful when it is invoked with the string "default". The Xlib documentation nowhere states that this is a valid value for the backing store attribute. Am I missing something? Regards, -- Oliver Laumann net@TUB.BITNET net@tub.UUCP

I wanted a way of indicating that the backing store attribute in the window not be specified in the SetWindowAttributes; the R3 servers have a hack option (-wm) which turns WhenMapped backing store on all windows which don't specify an explicit value. Obviously your code will need to recognise the magic value and handle it specially. Good thing there isn't any specification for the Xmu library.
