NAME
       XQueryBestSize, XQueryBestTile, XQueryBestStipple - determine effi-
       cient sizes

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

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

       Status XQueryBestStipple(Display *display, Drawable which_screen,
	      unsigned int width, unsigned int height, unsigned int
	      *width_return, unsigned int *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 Tile-
       Shape, 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 Stipple-
       Shape, 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 win-
       dow 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 win-
       dow 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 Win-
		 dow 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 speci-
		 fied for an argument, the full range defined by the argu-
		 ment’s type is accepted.  Any argument defined as a set of
		 alternatives can generate this error.
