Description
  XSetWMIconName()  performs  an XSetTextProperty() to set the XA_WM_ICON_NAME property of the specified window.  XSetWMIconName() supersedes
  XSetIconName().

  This is usually called by an application to set the property for the window manager.	The name should be short, since it is to be displayed
  in association with an icon.

  XSetStandardProperties() (in Release 3) or XSetWMProperties() (in Release 4 and later) also set this property.

  For more information, see Volume One, Chapter 12, Interclient Communication.

Structures
     typedef struct {
	 unsigned char *value;		/* same as Property routines */
	 Atom encoding; 		/* prop type */
	 int format;			/* prop data format: 8, 16, or 32 */
	 unsigned long nitems;		/* number of data items in value */
     } XTextProperty;
