.Sh DESCRIPTION
|
||
|
|
These routines are used for describing the
|
||
|
|
RPC messages in XDR language.
|
||
|
|
They should normally be used by those who do not
|
||
|
|
want to use the RPC
|
||
|
|
package directly.
|
||
|
|
These routines return
|
||
|
|
.Dv TRUE
|
||
|
|
if they succeed,
|
||
|
|
.Dv FALSE
|
||
|
|
otherwise.
|
||
|

|
See
|

|
|
.Xr rpc 3
|
||
|
|
for the definition of the
|
||
|
|
.Vt XDR
|
||
|
|
data structure.

|
.Bl -tag -width XXXXX
|
||
|
|
.It Fn xdr_accepted_reply
|
||
|
|
Used to translate between RPC
|
||
|
|
reply messages and their external representation.
|
||
|
|
It includes the status of the RPC
|
||
|
|
call in the XDR language format.
|
||
|
|
In the case of success, it also includes the call results.
|
||
|
|
.It Fn xdr_authsys_parms
|
||
|
|
Used for describing
|
||
|
|
.Ux
|
||
|
|
operating system credentials.
|
||
|
|
It includes machine-name, uid, gid list, etc.
|
||
|
|
.It Fn xdr_callhdr
|
||
|
|
Used for describing
|
||
|
|
RPC
|
||
|
|
call header messages.
|
||
|
|
It encodes the static part of the call message header in the
|
||
|
|
XDR language format.
|
||
|
|
It includes information such as transaction
|
||
|
|
ID, RPC version number, program and version number.
|
||
|
|
.It Fn xdr_callmsg
|
||
|
|
Used for describing
|
||
|
|
RPC call messages.
|
||
|
|
This includes all the RPC
|
||
|
|
call information such as transaction
|
||
|
|
ID, RPC version number, program number, version number,
|
||
|
|
authentication information, etc.
|
||
|
|
This is normally used by servers to determine information about the client
|
||
|
|
RPC call.
|
||
|
|
.It Fn xdr_opaque_auth
|
||
|
|
Used for describing RPC
|
||
|
|
opaque authentication information messages.
|
||
|
|
.It Fn xdr_rejected_reply
|
||
|
|
Used for describing RPC reply messages.
|
||
|
|
It encodes the rejected RPC message in the XDR language format.
|
||
|
|
The message could be rejected either because of version
|
||
|
|
number mis-match or because of authentication errors.
|
||
|
|
.It Fn xdr_replymsg
|
||
|
|
Used for describing RPC
|
||
|
|
reply messages.
|
||
|
|
It translates between the
|
||
|
|
RPC reply message and its external representation.
|
||
|
|
This reply could be either an acceptance,
|
||
|
|
rejection or
|
||
|
|
.Dv NULL .
