DESCRIPTION

34     These routines are a part of the RPC library which allows the RPC servers
35     to register themselves with rpcbind (see rpcbind(8)), and associate the
36     given program and version number with the dispatch function.  When the
37     RPC server receives a RPC request, the library invokes the dispatch rou‐
38     tine with the appropriate arguments.

Routines

41     See rpc(3) for the definition of the SVCXPRT data structure.
42
43     rpc_reg()
44            Register program prognum, procedure procname, and version versnum
45            with the RPC service package.  If a request arrives for program
46            prognum, version versnum, and procedure procnum, procname is
47            called with a pointer to its argument(s); procname should return a
48            pointer to its static result(s); inproc is the XDR function used
49            to decode the arguments while outproc is the XDR function used to
50            encode the results.  Procedures are registered on all available
51            transports of the class nettype.  See rpc(3).  This routine
52            returns 0 if the registration succeeded, -1 otherwise.
53
54     svc_reg()
55            Associates prognum and versnum with the service dispatch proce‐
56            dure, dispatch.  If netconf is NULL, the service is not registered
57            with the rpcbind(8) service.  If netconf is non-zero, then a map‐
58            ping of the triple [prognum, versnum, netconf->nc_netid] to
59            xprt->xp_ltaddr is established with the local rpcbind service.
60
61            The svc_reg() routine returns 1 if it succeeds, and 0 otherwise.
62
63     svc_unreg()
64            Remove from the rpcbind service, all mappings of the triple
65            [prognum, versnum, all-transports] to network address and all map‐
66            pings within the RPC service package of the double [prognum,
67            versnum] to dispatch routines.
68
69     svc_auth_reg()
70            Registers the service authentication routine handler with the dis‐
71            patch mechanism so that it can be invoked to authenticate RPC
72            requests received with authentication type cred_flavor.  This
73            interface allows developers to add new authentication types to
74            their RPC applications without needing to modify the libraries.
75            Service implementors usually do not need this routine.
