SYNTAX
       Status XQueryBestSize(display, class, whichscreen, width,
       height, widthreturn, heightreturn)
             Display *display;

       Status XQueryBestStipple(display, whichscreen, width,
       height, widthreturn, heightreturn)
             Display *display;

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.

       whichscreen
                 Specifies any drawable on the screen.

       widthreturn
       heightreturn
                 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 indi-
       cates 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 spe-
                 cific 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.
