NAME

     XQueryBestSize, XQueryBestTile, XQueryBestStipple - deter-
     mine efficient 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 Stip-
               pleShape.

     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 draw-
     able for TileShape or StippleShape, or a BadMatch error
     results.

XQueryBestSize(3X11)     XLIB FUNCTIONS      XQueryBestSize(3X11)

     XQueryBestSize can generate BadDrawable, BadMatch, and Bad-
     Value 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 Inpu-
     tOnly 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 Inpu-
     tOnly 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 gen-
               erate this error.
