Name of window system through which the selected frame is displayed.

The value is a symbol:
 nil for a termcap frame (a character-only terminal),
 x for an Emacs frame that is really an X window,
 w32 for an Emacs frame that is a window on MS-Windows display,
 ns for an Emacs frame on a GNUstep or Macintosh Cocoa display,
 pc for a direct-write MS-DOS frame.
