Could someone pls tell me how to read a subdirectory under MeSsDOS 3.3?

I have been trying the handle reads as Turbo C supports them, but MeSsDOS
refuses to open the files (ERR:  Access Denied).  If I need to ue the
read via fcb, could someone pls tell me how these interrupts work (I've
spent a long time looking thru inter489, and still don't undersstand how
to read x bytes from an fcb-specified file.)

Of course, if possible, it would also be nice to know how to write subdirs.
I know the directory format, and I know how to read the root dir...

Any solutions in C / assembler would be appreciated, as long as they actually
read the directory file.  (I.e. doing a findfirst() findnext() sequence is
not OK, because of how slow these calls are...  I have a DI 0.5 (NU4.5)
hard drive, and thus I cannot use this slow method...)

Pls reply thru email to:

and not to the poster, nor by posting followups as I don't read the net
anymore.
