Where are the FileAttributes flags defined and/or documented for VC?
The information seems to be available here via .NET (see community comment for values), but I'd rather have a C header to refer to in my code:

History
Special meaning for certain values...

Specifying zero for any of the values will cause that value to not be updated.

Specifying -1 for LastAccessTime, ChangeTime, or LastWriteTime indicates that operations on the current handle should not affect the given field.  (I.e, specifying -1 for LastWriteTime will leave the LastWriteTime unaffected by writes performed on the current handle.)

This behavior is documented in the WDK, Installable File System section.
