No, it's not documented in the MSC manuals, and I have never been able to
write 0 bytes to DOS through the C write()-call. But, that writing 0
bytes will set current file size is well documented in MS DOS tech. ref.
and other techinical MS DOS manuals and books, and the fact that
MicroSoft could not help you says more about MS than the write system
call.
