l3tol(3)l3tol(3)Name
l3tol, ltol3 - convert between 3-byte integers and long integers
Syntax
void l3tol (lp, cp, n)
long ∗lp;
char ∗cp;
int n;
void ltol3 (cp, lp, n)
char ∗cp;
long ∗lp;
int n;
Description
The subroutine 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.
The 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.
Restrictions
Because of possible differences in byte ordering, the numerical values
of the long integers are machine-dependent.
