- cursor);
- int XUndefineCursor(Display *display, Window w);
- cursor
- Specifies
the cursor that is to be displayed or None.
- display
- Specifies the connection
to the X server.
- w

If a cursor is set, it
will be used when the pointer is in the window. If the cursor is None,
it is equivalent to XUndefineCursor.
XDefineCursor can generate BadCursor
and BadWindow errors.
The XUndefineCursor function undoes the effect
of a previous XDefineCursor for this window. When the pointer is in the
window, the parent's cursor will now be used. On the root window, the default
cursor is restored.
XUndefineCursor can generate a BadWindow error.
