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). 

BUGS

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