L3TOL (3C) L3TOL (3C)
NAME
13tol, 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
UJtol 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 .
Ltol8 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.
