l3tol(3C)

convert between 3-byte integers and long integers

From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

NAME

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

#include <stdlib.h>

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

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

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.

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