Win32       3. Linux       4. OS/2       5. PDOS-generic              Using different methods of implementation.              1 and 3 are done by servicing the interrupts       (mainly INT 21H and INT 80H)              Win32 intercepts the C library MSVCRT              OS/2 intercepts the OS/2 system calls at       the DLL interface (doscalls.dll)              PDOS-generic passes the callback functions as       a stack parameter.              BFN.
