2 * internal pidl functions
3 * 1998 <juergen.schmied@metronet.de>
5 * DO NOT use this definitions outside the shell32.dll !
7 * The contents of a pidl should never used from a application
10 * This stuff is used from SHGetFileAttributes, ShellFolder
11 * EnumIDList and ShellView.
20 * the pidl does cache fileattributes to speed up SHGetAttributes when
21 * displaying a big number of files.
23 * a pidl of NULL means the desktop
25 * The structure of the pidl seems to be a union. The first byte of the
26 * PIDLDATA desribes the type of pidl.
28 * object ! first byte / ! format ! living space
