NAME
XRecolorCursor, XFreeCursor, XQueryBestCursor - manipulate cursors
SYNTAX
int XRecolorCursor(Display *display, Cursor cursor, XColor *fore-
ground_color, XColor *background_color);
int XFreeCursor(Display *display, Cursor cursor);
Status XQueryBestCursor(Display *display, Drawable d, unsigned int
width, unsigned int height, unsigned int *width_return, unsigned
int *height_return);
ARGUMENTS
background_color
Specifies the RGB values for the background of the source.
cursor Specifies the cursor.
d Specifies the drawable, which indicates the screen.
display Specifies the connection to the X server.
foreground_color
Specifies the RGB values for the foreground of the source.
width
height Specify the width and height of the cursor that you want the
size information for.
width_return
height_return
Return the best width and height that is closest to the spec-

DESCRIPTION
The XRecolorCursor function changes the color of the specified cursor,
and if the cursor is being displayed on a screen, the change is visible
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 re-
source 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 cur-
sors on displays that cannot support large ones.
XQueryBestCursor can generate a BadDrawable error.
DIAGNOSTICS
BadCursor A value for a Cursor argument does not name a defined Cursor.
BadDrawable
A value for a Drawable argument does not name a defined Win-
dow or Pixmap.
