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
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
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
Window or Pixmap.
