Hi all,

I'm implementing some DLLs to allow third party applications to control
machines via serial lines.  The DLLs use CRT routines (malloc,free) and are
currently statically linked to their own version of CRTs.
I'm wondering whether those statically linked CRTs are the correct way to do
it or may even cause errors (in fact there is currently a hang situation
reported).

Could someone explain the use of the subsystem library (compile switch /Rn)
and whether it's use would be better in my case.  And please remember that I
have a thread hidden inside the DLLs (currently started via _beginthread but
/Rn doesn't support it, DosStartThread plus some magic code required?).

Hoping for enlightenment,
    Vitus
