38 * Current scheme to create/open connection:
39 * 1. ncp_li_init() - lookup -S [-U] options in command line
40 * 2. ncp_li_init() - try to find existing connection
41 * 3. ncp_li_init() - if no server name and no accessible connections - bail out
42 * 4. This is connection candidate, read .rc file, override with command line
44 * Note: connection referenced only via ncp_login() call. Although it is
45 * possible to get connection handle in other way, it will be unwise to use
46 * it, since conn can be destroyed at any time.
