       XDefineCursor, XUndefineCursor - define cursors


       int XDefineCursor(Display *display, Window w, Cursor 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         Specifies the window.


       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.


       BadAlloc  The server failed to allocate the requested resource or server memory.

       BadCursor A value for a Cursor argument does not name a defined Cursor.

       BadWindow A value for a Window argument does not name a defined Window.
