L3TOL(3C) (C Programming Language Utilities) L3TOL(3C)
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(4).
CAVEAT
Because of possible differences in byte ordering, the
numerical values of the long integers are machine-dependent.
