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 suc

ceed, FALSE otherwise.

Routines

See rpc(3) for the definition of the XDR data structure.

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 in

cludes the
call results.

xdr_authsys_parms()

Used for describing UNIX operating system creden

tials. It
includes machine-name, uid, gid list, etc.

xdr_callhdr()

Used for describing RPC call header messages. It en

codes 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.

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 informa

tion, etc.
This is normally used by servers to determine infor

mation about
the client RPC call.

xdr_opaque_auth()

Used for describing RPC opaque authentication infor

mation messages.

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.

xdr_replymsg()

Used for describing RPC reply messages. It trans

lates between the
RPC reply message and its external representation.

This reply
could be either an acceptance, rejection or NULL.
