l3tol(3C) l3tol(3C)

NAME

l3tol(), ltol3() - convert between 3-byte integers and long integers

SYNOPSIS

#include <stdlib.h>

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

void ltol3(char *cp, const long int *lp, int n);

DESCRIPTION

l3tol() Convert 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() Perform 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.

APPLICATION USAGE

l3tol() and ltol3() are thread-safe and async-cancel-safe.

WARNINGS

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

dependent.
