2203 * value in a window's extra memory.
2205 * The _hwnd_ parameter specifies the window. is the handle to a
2206 * window that has extra memory. The _newval_ parameter contains the
2207 * new attribute or extra memory value. If positive, the _offset_
2208 * parameter is the byte-addressed location in the window's extra
2209 * memory to set. If negative, _offset_ specifies the window
2210 * attribute to set, and should be one of the following values:
2212 * GWL_EXSTYLE The window's extended window style
2214 * GWL_STYLE The window's window style.
2216 * GWLP_WNDPROC Pointer to the window's window procedure.
2218 * GWLP_HINSTANCE The window's pplication instance handle.
2220 * GWLP_ID The window's identifier.
2222 * GWLP_USERDATA The window's user-specified data.
2224 * If the window is a dialog box, the _offset_ parameter can be one of
2225 * the following values:
2227 * DWLP_DLGPROC The address of the window's dialog box procedure.
2229 * DWLP_MSGRESULT The return value of a message
2230 * that the dialog box procedure processed.
2232 * DWLP_USER Application specific information.
2236 * If successful, returns the previous value located at _offset_. Otherwise,
2241 * Extra memory for a window class is specified by a nonzero cbWndExtra
2242 * parameter of the WNDCLASS structure passed to RegisterClass() at the
2243 * time of class creation.
2245 * Using GWL_WNDPROC to set a new window procedure effectively creates
2246 * a window subclass. Use CallWindowProc() in the new windows procedure
2247 * to pass messages to the superclass's window procedure.
2249 * The user data is reserved for use by the application which created
