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

SYNOPSIS
      #include <stdlib.h>

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

      void ltol3 (char *cp, const 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).

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