The solution to your problem is to use DosQFSAttach as a Run-Time API-Call.
First you check your version number of OS/2 then you make calls to 
DosLoadModule (check your system DLL's for DosQFSAttach) and DosGetProcAddr.
After this you can use DosQFSAttach. Be sure to free the Module with
DosFreeModule. For further information about Runtime-DLL's consult your
manuals (RTFM ;-)

   Bye,
