L3TOL(3) Library Functions Manual L3TOL(3)NAME
l3tol, ltol3 - convert between 3-byte and long integers (2BSD)
SYNOPSIS
l3tol(lp, cp, n)
long *lp;
char *cp;
ltol3(cp, lp, n)
char *cp;
long *lp;
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 inverse conversion from long integers (lp) to three-byte integers (cp).
These functions are useful for file-system maintenance under 2BSD where disk addresses within inodes are three bytes long.
SEE ALSO fs(5)BUGS
l3tol and ltol3 are unique to the PDP-11 and 2BSD; their use is discouraged.
