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 TRUE if they succeed, FALSE otherwise.
Sh ROUTINES
See
Xr rpc 3
for the definition of the
Vt XDR
data structure.
Pp
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.
Pp
It Fn xdr_authsys_parms
Used for describing UNIX operating system credentials.
It includes machine-name, uid, gid list, etc.
Pp
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.
Pp
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.
Pp
It Fn xdr_opaque_auth
Used for describing RPC
opaque authentication information messages.
Pp
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.
Pp
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 .
