23 * DO NOT use this definitions outside the shell32.dll !
25 * The contents of a pidl should never used from a application
29 * MS says: the abID of SHITEMID should be treated as binary data and not
30 * be interpreted by applications. Applies to everyone but MS itself.
31 * Word95 interprets the contents of abID (Filesize/Date) so we have to go
32 * for binary compatibility here.
46 * the pidl does cache fileattributes to speed up SHGetAttributes when
47 * displaying a big number of files.
49 * a pidl of NULL means the desktop
51 * The structure of the pidl seems to be a union. The first byte of the
52 * PIDLDATA describes the type of pidl.
