       _l_u_n_i_t must refer to an open logical unit.   _o_f_f_s_e_t  is  an
       offset  in  bytes  relative  to  the position specified by
       _f_r_o_m_.  Valid values for _f_r_o_m are:

            0 meaning `beginning of the file'
            1 meaning `the current position'
            2 meaning `the end of the file'

       The value returned by _f_s_e_e_k will be  0  if  successful,  a
       system error code otherwise.  (See perror(3F))

       _F_t_e_l_l  returns the current position of the file associated
       with the specified logical unit. The value is  an  offset,
       in  bytes,  from  the beginning of the file.  If the value
       returned is negative, it indicates an error  and  will  be
       the negation of the system error code. (See perror(3F))
