      NAME
           fseek, ftell - reposition a file on a logical unit

      SYNTAX
           integer function fseek (lunit, offset, from)
           integer offset, from

           integer function ftell (lunit)

      DESCRIPTION
           lunit must refer to an open logical unit.  offset is an
           offset in bytes relative to the position specified by from.
           Valid values for from are:

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

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

           Ftell 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))
