36.Sh DESCRIPTION
37These routines are used for describing the
38RPC messages in XDR language.
39They should normally be used by those who do not
40want to use the RPC
41package directly.
42These routines return TRUE if they succeed, FALSE otherwise.
43.Sh ROUTINES
44See
45.Xr rpc 3
46for the definition of the
47.Vt XDR
48data structure.
49.Pp
50.Bl -tag -width XXXXX
51.It Fn xdr_accepted_reply
52Used to translate between RPC
53reply messages and their external representation.
54It includes the status of the RPC
55call in the XDR language format.
56In the case of success, it also includes the call results.
57.Pp
58.It Fn xdr_authsys_parms
59Used for describing UNIX operating system credentials.
60It includes machine-name, uid, gid list, etc.
61.Pp
62.It Fn xdr_callhdr
63Used for describing
64.SM RPC
65call header messages.
66It encodes the static part of the call message header in the
67XDR language format.
68It includes information such as transaction
69ID, RPC version number, program and version number.
70.Pp
71.It Fn xdr_callmsg
72Used for describing
73RPC call messages.
74This includes all the  RPC
75call information such as transaction
76ID, RPC version number, program number, version number,
77authentication information, etc.
78This is normally used by servers to determine information about the client
79RPC call.
80.Pp
81.It Fn xdr_opaque_auth
82Used for describing RPC
83opaque authentication information messages.
84.Pp
85.It Fn xdr_rejected_reply
86Used for describing RPC reply messages.
87It encodes the rejected RPC message in the XDR language format.
88The message could be rejected either because of version
89number mis-match or because of authentication errors.
90.Pp
91.It Fn xdr_replymsg
92Used for describing RPC
93reply messages.  It translates between the
94RPC reply message and its external representation.
95This reply could be either an acceptance,
96rejection or
97.Dv NULL .
