- Handle 'empty' maps more gracefully. By empty I mean a valid map that just happens not to have any entries in it, such as you would get if you built a map database from an empty file. Previously, trying to ypxfr such a map would yield an 'NIS map/database error' which is not the correct behavior. ypxfr_misc: - Make sure to free() or xdr_free() dynamically allocated memory in ypxfr_get_master() as necessary.
