XQueryBestCursor()														XQueryBestCursor()

Name
  XQueryBestCursor - get the closest supported cursor sizes.

Synopsis
  Status XQueryBestCursor(display, d, width, height,
	    width_return, height_return)
	Display *display;
	Drawable d;
	unsigned int width, height;
	unsigned int *width_return, *height_return;

Arguments
  display	 Specifies a connection to an X server; returned from XOpenDisplay().

  d		 Specifies a drawable that indicates which screen the cursor is to be used on.	The best cursor may be different on different
		 screens.

  width 	 Specify the preferred width and height, in pixels.
  height

  width_return	 Returns the closest supported cursor dimensions, in pixels, on the display hardware.
  height_return
Returns
  Zero on failure, non-zero on success.

Description
  XQueryBestCursor() returns the closest cursor dimensions actually supported by the display hardware to the dimensions you specify.

  Call this function if you wish to use a cursor size other than 16 by 16.  XQueryBestCursor() provides a way to find out what	size  cursors
  are actually possible on the display.  Applications should be prepared to use smaller cursors on displays which cannot support large ones.

  XQueryBestCursor()  returns  non-zero if the call succeeded in getting a supported size (which may be the same or different from the speci-
  fied size), or zero if the call failed.

Errors
  BadDrawable

NAME

       XRecolorCursor, XFreeCursor, XQueryBestCursor - manipulate cursors

SYNOPSIS

       XRecolorCursor(display, cursor, foreground_color, background_color)
	       Display *display;
	       Cursor cursor;
	       XColor *foreground_color, *background_color;

       XFreeCursor(display, cursor)
	       Display *display;
	       Cursor cursor;

       Status XQueryBestCursor(display, d, width, height, width_return, height_return)
	       Display *display;
	       Drawable d;
	       unsigned int width, height;
	       unsigned int *width_return, *height_return;

ARGUMENTS

       Specifies  the  RGB  values  for  the background of the source.	Specifies the cursor.  Specifies the drawable, which indicates the screen.
       Specifies the connection to the X server.  Specifies the RGB values for the foreground of the source.  Specify the width and height of  the
       cursor that you want the size information for.  Return the best width and height that is closest to the specified width and height.

DESCRIPTION

       The XRecolorCursor function changes the color of the specified cursor, and if the cursor is being displayed on a screen, the change is vis-
       ible immediately. The pixel members of the XColor structures are ignored; only the RGB values are used.

       XRecolorCursor can generate a BadCursor error.

       The XFreeCursor function deletes the association between the cursor resource ID and the specified cursor. The cursor storage is freed  when
       no other resource references it. The specified cursor ID should not be referred to again.

       XFreeCursor can generate a BadCursor error.

       Some  displays  allow  larger  cursors  than other displays. The XQueryBestCursor function provides a way to find out what size cursors are
       actually possible on the display. It returns the largest size that can be displayed. Applications should be prepared to use smaller cursors
       on displays that cannot support large ones.

       XQueryBestCursor can generate a BadDrawable error.

DIAGNOSTICS

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