      NAME
           l3tol, ltol3 - convert between 3-byte integers and long
           integers

      SYNTAX
           void l3tol (lp, cp, n)
           long *lp;
           char *cp;
           int n;

           void ltol3 (cp, lp, n)
           char *cp;
           long *lp;
           int n;

      DESCRIPTION
           L3tol converts a list of n three-byte integers packed into a
           character string pointed to by cp into a list of long
           integers pointed to by lp.

           Ltol3 performs the reverse conversion from long integers
           (lp) to three-byte integers (cp).

           These functions are useful for file-system maintenance where
           the block numbers are three bytes long.

      SEE ALSO
           fs(4).

      BUGS
           Because of possible differences in byte ordering, the
           numerical values of the long integers are machine-dependent.
