NAME
        AddTOF - add a task to the VBlank interrupt server chain.

   SYNOPSIS
        AddTOF(i,p,a);

        VOID AddTOF(struct isrvstr *, aptr, aptr);

   FUNCTION
        Adds a task to the vertical-blanking interval interrupt server
        chain. This prevents C programmers from needing to write an
        assembly language stub to do this function.

   INPUTS
        i - pointer to an initialized isrvstr structure
        p - pointer to the C-code routine that this server is to call each
            time TOF happens
        a - pointer to the first longword in an array of longwords that
            is to be used as the arguments passed to your routine
            pointed to by p.
