X-Hacker.org- Ralf Brown's Interrupt List (Part 1,2) - int 2f - multiplex - dos 3+ internal - decrement sft reference count http://www.X-Hacker.org [<<Previous Entry] [^^Up^^] [Next Entry>>] [Menu] [About The Guide]
INT 2F - Multiplex - DOS 3+ internal - DECREMENT SFT REFERENCE COUNT
        AX = 1208h
        ES:DI -> SFT
Return: AX = new value of reference count
Note:   if the reference count was 1, it is set to FFFFh (since 0 indicates
          that the SFT is not in use).  It is the caller's responsibility to
          set the reference count to zero after cleaning up.
