DESCRIPTION
The XRecolorCursor function changes the color of the speci-
fied 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 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.

XRecolorCursor(3X11) XLIB FUNCTIONS XRecolorCursor(3X11)
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
BadCursor A value for a Cursor argument does not name a
defined Cursor.
BadDrawable

defined Window or Pixmap.
