XRotateWindowProperties()			     XRotateWindowProperties()

Name
  XRotateWindowProperties – rotate properties in the properties array.

Synopsis
  XRotateWindowProperties(display, w, properties, num_prop, npositions)
	Display *display;
	Window w;
	Atom properties[];
	int num_prop;
	int npositions;

Arguments
  display   Specifies	a  connection  to  an  X  server;  returned  from
	    XOpenDisplay().

  w	    Specifies the ID of the window whose  properties  are  to  be
	    rearranged.

  properties
	    Specifies the list of properties to be rotated.

  num_prop  Specifies the length of the properties array.

  npositions
	    Specifies  the  number  of	positions  to rotate the property
	    list.  The sign controls the direction of rotation.

Description
  XRotateWindowProperties() rotates the contents of an array  of  proper‐
  ties	on  a  window.	If the property names in the properties array are
  viewed as if they were numbered  starting  from  0  and  if  there  are
  num_prop  property  names  in	 the list, then the value associated with
  property name I becomes the value associated with property  name  (I	+
  npositions) mod num_prop, for all I from 0 to num_prop - 1.  Therefore,
  the sign of npositions controls the direction of rotation.  The  effect
  is to rotate the states by npositions places around the virtual ring of
  property names (right for positive npositions, left for negative nposi‐
  tion).

  If  npositions mod num_prop is non-zero, a PropertyNotify event is gen‐
  erated for each property, in the order listed.

  If a BadAtom, BadMatch, or BadWindow error is generated, no  properties
  are changed.

Errors
  BadAtom   Undefined atom in the property list.

  BadMatch  An	atom  appears  more  that once in the list or no property
	    with that name is defined for the window.

  BadWindow
