XRotateWindowProperties can generate BadAtom, BadMatch, and BadWindow errors. XDeleteProperty can generate BadAtom and BadWindow errors. BadAtom A value for an Atom argument does not name a defined Atom.

Unless a spe cific range is specified for an argument, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this error. BadWindow A value for a Window argument does not name a defined Window.
