2745 * The _hwnd_ parameter specifies the handle to a window that

2747 * attribute or extra memory value. If positive, the _offset_
2748 * parameter is the byte-addressed location in the window's extra
2749 * memory to set. If negative, _offset_ specifies the window
2750 * attribute to set, and should be one of the following values:
2752 * GWL_EXSTYLE The window's extended window style
2754 * GWL_STYLE The window's window style.
2756 * GWLP_WNDPROC Pointer to the window's window procedure.
2758 * GWLP_HINSTANCE The window's application instance handle.
2760 * GWLP_ID The window's identifier.
2762 * GWLP_USERDATA The window's user-specified data.

2765 * the following values:
2767 * DWLP_DLGPROC The address of the window's dialog box procedure.
2769 * DWLP_MSGRESULT The return value of a message
2770 * that the dialog box procedure processed.
2772 * DWLP_USER Application specific information.
2776 * If successful, returns the previous value located at _offset_. Otherwise,
2781 * Extra memory for a window class is specified by a nonzero cbWndExtra
2782 * parameter of the WNDCLASS structure passed to RegisterClass() at the
2783 * time of class creation.
2785 * Using GWL_WNDPROC to set a new window procedure effectively creates
2786 * a window subclass. Use CallWindowProc() in the new windows procedure
2787 * to pass messages to the superclass's window procedure.
2789 * The user data is reserved for use by the application which created
