NAME
     XDefineCursor, XUndefineCursor - define cursors

SYNTAX
     XDefineCursor(display, w, cursor)
           Display *display;
           Window w;
           Cursor cursor;

     XUndefineCursor(display, w)
           Display *display;
           Window w;

ARGUMENTS
     cursor    Specifies the cursor that is to be displayed or None.

     display   Specifies the connection to the X server.

     w         Specifies the window.

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 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.

DIAGNOSTICS
     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.
