323 324 325 326

 *
 * Data which must be written on stream is:
327
 * 1) WORD constant: zero (not validated by Windows)
328 329
 * 2) length of the path string ("\0" included)
 * 3) path string type A
330 331 332 333 334
 * 4) Unknown WORD value: Frequently 0xFFFF, but not always. If set very large,
 *     Windows returns E_OUTOFMEMORY
 * 5) WORD Constant: 0xDEAD (not validated by Windows)
 * 6) five DWORD constant: zero (not validated by Windows)
 * 7) If we're only writing the multibyte version,
335 336
 *     write a zero DWORD and finish.
 *
337
 * 8) DWORD: double-length of the path string type W ("\0" not
