ARGUMENTS
- cursor
- Specifies the cursor that is to be displayed or
None.
- display
- Specifies the connection to the X server.
- w

DESCRIPTION
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.
