address' and subnet' are now arrays of GLIBTOP_IFADDR_LEN u_int8_t

Browse Source 
2000-01-24  Martin Baulig  <martin@home-of-linux.org>

	* include/glibtop/netinfo.h (glibtop_netinfo): `address' and
	`subnet' are now arrays of GLIBTOP_IFADDR_LEN u_int8_t values.
	(glibtop_get_netinfo): `transport' is now `u_int64_t' and not
	`unsigned' to make it work with `GLIBTOP_TRANSPORT_ALL'.

	* include/glibtop/limits.h (GLIBTOP_IFADDR_LEN): New constant.
	This is the length of a network interface address in bytes.
