Define Documentation

#define RTA_NEXT	(	rta,
		attrlen		)

Value:

((attrlen) -= RTA_ALIGN((rta)->rta_len), \
(struct rtattr *) (((char *)(rta)) + RTA_ALIGN((rta)->rta_len)))

#define RTA_OK	(	rta,
		len		)

Value:

((len) > 0 && (rta)->rta_len >= sizeof(struct rtattr) && \
(rta)->rta_len <= (len))
