36 | * YPSERV PROTOCOL: |

37 | * |
---|
38 | * ypserv supports the following procedures: |
---|
39 | * |
---|
40 | * YPPROC_NULL takes (void), returns (void). |
---|
41 | * called to check if server is alive. |
---|
42 | * YPPROC_DOMAIN takes (char *), returns (bool_t). |
---|
43 | * true if ypserv serves the named domain. |
---|
44 | * YPPROC_DOMAIN_NOACK takes (char *), returns (bool_t). |
---|
45 | * true if ypserv serves the named domain. |
---|
46 | * used for broadcasts, does not ack if ypserv |
---|
47 | * doesn't handle named domain. |
---|
48 | * YPPROC_MATCH takes (struct ypreq_key), returns (struct ypresp_val) |
---|
49 | * does a lookup. |
---|
50 | * YPPROC_FIRST takes (struct ypreq_nokey) returns (ypresp_key_val). |
---|
51 | * gets the first key/datum from the map. |
---|
52 | * YPPROC_NEXT takes (struct ypreq_key) returns (ypresp_key_val). |
---|
53 | * gets the next key/datum from the map. |
---|
54 | * YPPROC_XFR takes (struct ypreq_xfr), returns (void). |
---|
55 | * tells ypserv to check if there is a new version of |
---|
56 | * the map. |
---|
57 | * YPPROC_CLEAR takes (void), returns (void). |
---|
58 | * tells ypserv to flush it's file cache, so that |
---|
59 | * newly transferred files will get read. |
---|
60 | * YPPROC_ALL takes (struct ypreq_nokey), returns (bool_t and |
---|
61 | * struct ypresp_key_val). |
---|
62 | * returns an array of data, with the bool_t being |
---|
63 | * false on the last datum. read the source, it's |
---|
64 | * convoluted. |
---|
65 | * YPPROC_MASTER takes (struct ypreq_nokey), returns (ypresp_master). |
---|
66 | * YPPROC_ORDER takes (struct ypreq_nokey), returns (ypresp_order). |
---|
67 | * YPPROC_MAPLIST takes (char *), returns (struct ypmaplist *). |
