MS-DOS filters in Borland Turbo C: help request.

[Stanislaw L. Olejniczak]

I would LIKE to write a tee like program/filter for DOS.  The only thing I have
left is some way to determine whether the program is being used as a filter:
C> type myfile | tee
or as an executable
C> tee myfile
I am using Borland Turbo C 1.5 under MS-DOS 3.2.  Any suggestions will be
greatly appreciated.
(Any references to more detailed information about MS-DOS filters would also be
greatly appreciated).  Thanks
