  width_return, height_return)
	  Display *display;
	  int class;
	  Drawable which_screen;
	  unsigned int width, height;
	  unsigned int *width_return, *height_return;

  Status XQueryBestTile(display, which_screen, width, height, width_return,
  height_return)
	  Display *display;
	  Drawable which_screen;
	  unsigned int width, height;
	  unsigned int *width_return, *height_return;

  Status XQueryBestStipple(display, which_screen, width, height,
  width_return, height_return)
	  Display *display;
	  Drawable which_screen;
	  unsigned int width, height;
	  unsigned int *width_return, *height_return;


ARGUMENTS

  class
      Specifies the class that you are interested in. You can pass TileShape,
      CursorShape, or StippleShape.

  display
      Specifies the connection to the X server.

  width

  height
      Specify the width and height.

  which_screen
      Specifies any drawable on the screen.

  width_return

  height_return
      Return the width and height of the object best supported by the display
      hardware.


DESCRIPTION

  The XQueryBestSize function returns the best or closest size to the
  specified size. For CursorShape, this is the largest size that can be fully
  displayed on the screen specified by which_screen.  For TileShape, this is
  the size that can be tiled fastest.  For StippleShape, this is the size
  that can be stippled fastest. For CursorShape, the drawable indicates the
  desired screen. For TileShape and StippleShape, the drawable indicates the
  screen and possibly the window class and depth.  An InputOnly window cannot
  be used as the drawable for TileShape or StippleShape, or a BadMatch error
  results.

  XQueryBestSize can generate BadDrawable, BadMatch, and BadValue errors.

  The XQueryBestTile function returns the best or closest size, that is, the
  size that can be tiled fastest on the screen specified by which_screen. The
  drawable indicates the screen and possibly the window class and depth. If
  an InputOnly window is used as the drawable, a BadMatch error results.

  XQueryBestTile can generate BadDrawable and BadMatch errors.

  The XQueryBestStipple function returns the best or closest size, that is,
  the size that can be stippled fastest on the screen specified by
  which_screen. The drawable indicates the screen and possibly the window
  class and depth. If an InputOnly window is used as the drawable, a BadMatch
  error results.

  XQueryBestStipple can generate BadDrawable and BadMatch errors.


DIAGNOSTICS

  BadMatch
	  An InputOnly window is used as a Drawable.

  BadDrawable
	  A value for a Drawable argument does not name a defined Window or
	  Pixmap.

  BadMatch
	  The values do not exist for an InputOnly window.

  BadValue
	  Some numeric value falls outside the range of values accepted by
	  the request. Unless a specific 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.
