L3TOL(3C-SVR3)      RISC/os Reference Manual       L3TOL(3C-SVR3)



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

SYNOPSIS
     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.ffs(4).

CAVEAT
     Because of possible differences in byte ordering, the numer-
     ical values of the long integers are machine-dependent.
