l3tol(3C) — C LIBRARY FUNCTIONS
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
NOTES
Because of possible differences in byte ordering, the numerical values of the long integers are machine-dependent.
