get_xatom_name
Description:
Returns the name of an X atom for GDK’s default display.
 This function is meant mainly for debugging, so for convenience, unlike XAtomName and 
      name, the result doesn’t need to be freed. Also, this function will never return 
      null, even if xatom is invalid.
Parameters:
| xatom | 
           an X atom for GDK’s default display  | 
      
Returns:
| 
           name of the X atom; this string is owned by GTK+, so it shouldn’t be modifed or freed.  |
