Did Microsoft document this somewhere?

ie before calling FindFirst, you should SET the DTA to point to
a 43-byte buffer?

If not, how are you supposed to know something like this?
ie that Microsoft guarantees that you only need 43 bytes
for eternity. And that it doesn't need to be aligned on any
particular boundary (2/4/8/16/32 bytes).

Thanks. Paul.
