23 The getrpcent(), getrpcbyname(), and getrpcbynumber() functions each
24 return a pointer to an object with the following structure containing
25 the broken-out fields of an entry in the RPC program number data base.
26
27 struct rpcent {
28 char *r_name; /* name of server for this RPC program */
29 char **r_aliases; /* alias list */
30 long r_number; /* RPC program number */
31 };
32
33 The members of this structure are:
34
35 r_name The name of the server for this RPC program.
36
37 r_aliases A NULL-terminated list of alternate names for the RPC
38 program.
39
40 r_number The RPC program number for this service.
41
42 The getrpcent() function reads the next entry from the database. A
43 connection is opened to the database if necessary.
44
45 The setrpcent() function opens a connection to the database, and sets
46 the next entry to the first entry. If stayopen is nonzero, then the
47 connection to the database will not be closed between calls to one of
48 the getrpc*() functions.
49
50 The endrpcent() function closes the connection to the database.
51
52 The getrpcbyname() and getrpcbynumber() functions sequentially search
53 from the beginning of the file until a matching RPC program name or
54 program number is found, or until end-of-file is encountered.
55
57 On success, getrpcent(), getrpcbyname(), and getrpcbynumber() return a
58 pointer to a statically allocated rpcent structure. A NULL pointer is
59 returned on EOF or error.
