XDefineCursor(3X11)						  XLIB FUNCTIONS					       XDefineCursor(3X11)

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 function undoes the effect of a previous XDefineCursor for this window.  When the pointer is in the window, the par-
       ent'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.
