calls
SYNTAX AND DESCRIPTION
These routines let C programs make procedure calls on other
machines across the network. First, the client calls a
procedure to send a data packet to the server. Upon receipt
of the packet, the server calls a dispatch routine to
perform the requested service, and then sends back a reply.
Finally, the procedure call returns to the client.
#include <rpc/rpc.h>
void
authdestroy(auth)
AUTH *auth;
A macro that destroys the authentication information
associated with auth. Destruction usually involves
deallocation of private data structures. The use of
auth is undefined after calling authdestroy().
AUTH *
authnonecreate()
Create and returns an RPC authentication handle that
passes nonusable authentication information with each
remote procedure call. This is the default
authentication used by RPC.

struct sockaddr *syncaddr;
desblock *ckey;
NOTE: Secure RPC using DES Authentication is an additional
feature that must be purchased separately from the DG/UXTM
ONCTM/NFS product.
authdescreate() is the first of two routines which
interface to the RPC secure authentication system,
known as DES authentication. The second is
authdesgetucred(), below. Note: the keyserver daemon
keyserv(8) must be running for the DES authentication
system to work.
authdescreate(), used on the client side, returns an
authentication handle that will enable the use of the
secure authentication system. The first parameter name
is the network name, or netname, of the owner of the
server process. This field usually represents a
hostname derived from the utility routine host2netname,
but could also represent a user name using
user2netname. The second field is window on the
validity of the client credential, given in seconds. A
small window is more secure than a large one, but
choosing too small of a window will increase the
frequency of resynchronizations because of clock drift.
The third parameter syncaddr is optional. If it is
NULL, then the authentication system will assume that
the local clock is always in sync with the server's
clock, and will not attempt resynchronizations. If an
address is supplied, however, then the system will use
the address for consulting the remote time service
whenever resynchronization is required. This parameter
is usually the address of the RPC server itself. The
final parameter ckey is also optional. If it is NULL,
then the authentication system will generate a random
DES key to be used for the encryption of credentials.
If it is supplied, however, then it will be used
instead.
authdesgetucred(adc, uid, gid, grouplen, groups)
struct authdescred *adc;
short *uid;
short *gid;
short *grouplen;
int *groups;
authdesgetucred(), the second of the two DES
authentication routines, is used on the server side for
Licensed material--property of copyright holder(s) Page 2
rpc(3N) DG/UX 4.30 rpc(3N)
converting a DES credential, which is operating system
independent, into a UNIX credential. This routine
differs from utility routine netname2user in that
authdesgetucred() pulls its information from a cache,
and does not have to do a Yellow Pages lookup everytime
it is called to get its information.
AUTH *
authunixcreate(host, uid, gid, len, aupgids)
char *host;
int uid, gid, len, *aup.gids;
Create and return an RPC authentication handle that
contains UNIX authentication information. The
parameter host is the name of the machine on which the
information was created; uid is the user's user ID ;
gid is the user's current group ID ; len and aup_gids
refer to a counted array of groups to which the user
belongs. It is easy to impersonate a user.
AUTH *
authunixcreatedefault()
Calls authunixcreate() with the appropriate
parameters.
callrpc(host, prognum, versnum, procnum, inproc, in, outproc, out)
char *host;
ulong prognum, versnum, procnum;
char *in, *out;
xdrproct inproc, outproc;
Call the remote procedure associated with prognum,
versnum, and procnum on the machine, host. The
parameter in is the address of the procedure's
argument(s), and out is the address of where to place
the result(s); inproc is used to encode the procedure's
parameters, and outproc is used to decode the
procedure's results. This routine returns zero if it
succeeds, or the value of enum clntstat cast to an
integer if it fails. The routine clntperrno() is
handy for translating failure statuses into messages.
Warning: calling remote procedures with this routine
uses UDP/IP as a transport; see clntudpcreate() for
restrictions. You do not have control of timeouts or
authentication using this routine.
enum clntstat
clntbroadcast(prognum, versnum, procnum, inproc, in, outproc,
out, eachresult)
ulong prognum, versnum, procnum;
Licensed material--property of copyright holder(s) Page 3
rpc(3N) DG/UX 4.30 rpc(3N)
char *in, *out;
xdrproct inproc, outproc;
resultproct eachresult;
Like callrpc(), except the call message is broadcast to
all locally connected broadcast nets. Each time it
receives a response, this routine calls eachresult(),
whose form is:
eachresult(out, addr)
char *out;
struct sockaddrin *addr;
where out is the same as out passed to
clntbroadcast(), except that the remote procedure's
output is decoded there; addr points to the address of
the machine that sent the results. If eachresult()
returns zero, clntbroadcast() waits for more replies;
otherwise it returns with appropriate status.
Warning: broadcast sockets are limited in size to the
maximum transfer unit of the data link. For ethernet,
this value is 1500 bytes.
enum clntstat
clntcall(clnt, procnum, inproc, in, outproc, out, tout)
CLIENT *clnt;
ulong
procnum;
xdrproct inproc, outproc;
char *in, *out;
struct timeval tout;
A macro that calls the remote procedure procnum
associated with the client handle, clnt, which is
obtained with an RPC client creation routine such as
clntcreate(). The parameter in is the address of the
procedure's argument(s), and out is the address of
where to place the result(s); inproc is used to encode
the procedure's parameters, and outproc is used to
decode the procedure's results; tout is the time
allowed for results to come back.
clntdestroy(clnt)
CLIENT *clnt;
A macro that destroys the client's RPC handle.
Destruction usually involves deallocation of private
data structures, including clnt itself. Use of clnt is
undefined after calling clntdestroy(). If the RPC
library opened the associated socket, it will close it
Licensed material--property of copyright holder(s) Page 4
rpc(3N) DG/UX 4.30 rpc(3N)
also. Otherwise, the socket remains open.
CLIENT *
clntcreate(host, prog, vers, proto)
char *host;
ulong prog, vers;
char *proto;
Generic client creation routine. host identifies the
name of the remote host where the server is located.
proto indicates which kind of transport protocol to
use. The currently supported values for this field are
udp and tcp. Default timeouts are set, but can be
modified using clntcontrol().
Warning: Using UDP has its shortcomings. Since UDP-
based RPC messages can only hold up to 8 Kbytes of
encoded data, this transport cannot be used for
procedures that take large arguments or return huge
results.
boolt
clntcontrol(cl, req, info)
CLIENT *cl;
char *info;
A macro used to change or retrieve various information
about a client object. req indicates the type of
operation, and info is a pointer to the information.
For both UDP and TCP, the supported values of req and
their argument types and what they do are:
CLSET_TIMEOUT struct
timeval set
total
timeout
CLGET_TIMEOUT struct
timeval get
total
timeout
Note: if you set the timeout using clntcontrol(), the
timeout parameter passed to clntcall() will be ignored
in all future calls.
CLGET_SERVER_ADDR struct
sockaddr get
server's
address
Licensed material--property of copyright holder(s) Page 5
rpc(3N) DG/UX 4.30 rpc(3N)
The following operations are valid for UDP only:
CLSET_RETRY_TIMEOUT struct
timeval set
the
retry
timeout
CLGET_RETRY_TIMEOUT struct
timeval get
the
retry
timeout
The retry timeout is the time that UDP RPC waits for
the server to reply before retransmitting the request.
clntfreeres(clnt, outproc, out)
CLIENT *clnt;
xdrproct outproc;
char *out;
A macro that frees any data allocated by the RPC/XDR
system when it decoded the results of an RPC call. The
parameter out is the address of the results, and
outproc is the XDR routine describing the results.
This routine returns one if the results were
successfully freed, and zero otherwise.
void
clntgeterr(clnt, errp)
CLIENT *clnt;
struct rpcerr *errp;
A macro that copies the error structure out of the
client handle to the structure at address errp.
void
clntpcreateerror(s)
char *s;
Print a message to standard error indicating why a
client RPC handle could not be created. The message is
prepended with string s and a colon. Used when a
clntcreate(), clntrawcreate(), clnttcpcreate(), or
clntudpcreate() call fails.
void
clntperrno(stat)
enum clntstat stat;
Print a message to standard error corresponding to the
Licensed material--property of copyright holder(s) Page 6
rpc(3N) DG/UX 4.30 rpc(3N)
condition indicated by stat. Used after callrpc().
clntperror(clnt, s)
CLIENT *clnt;
char *s;
Print a message to standard error indicating why an RPC
call failed; clnt is the handle used to do the call.
The message is prepended with string s and a colon.
Used after clntcall().
char *
clntspcreateerror
char *s;
Like clntpcreateerror(), except that it returns a
string instead of printing to the standard error.
Bugs: returns pointer to static data that is
overwritten on each call.
char *
clntsperrno(stat)
enum clntstat stat;
Take the same arguments as clntperrno(), but instead
of sending a message to the standard error indicating
why an RPC call failed, return a pointer to a string
which contains the message. The string ends with a
NEWLINE.
clntsperrno() is used instead of clntperrno() if the
program does not have a standard error (as a program
running as a server quite likely does not), or if the
programmer does not want the message to be output with
printf, or if a message format different than that
supported by clntperrno() is to be used. Note: unlike
clntsperror() and clntspcreaterror(), clntsperrno()
does not return pointer to static data so the result
will not get overwritten on each call.
char *
clntsperror(rpch, s)
CLIENT *rpch;
char *s;
Like clntperror(), except that (like clntsperrno())
it returns a string instead of printing to standard
error.
Bugs: returns pointer to static data that is
overwritten on each call.

CLIENT *
clntrawcreate(prognum, versnum)
ulong prognum, versnum;
This routine creates a toy RPC client for the remote
program prognum, version versnum. The transport used
to pass messages to the service is actually a buffer
within the process's address space, so the
corresponding RPC server should live in the same
address space; see svcrawcreate(). This allows
simulation of RPC and acquisition of RPC overheads,
such as round trip times, without any kernel
interference. This routine returns NULL if it fails.
CLIENT *
clnttcpcreate(addr, prognum, versnum, sockp, sendsz, recvsz)
struct sockaddrin *addr;
ulong prognum, versnum;
int *sockp;
uint sendsz, recvsz;
This routine creates an RPC client for the remote
program prognum, version versnum; the client uses
TCP/IP as a transport. The remote program is located at
Internet address *addr. If addr->sinport is zero,
then it is set to the actual port that the remote
program is listening on (the remote portmap service is
consulted for this information). The parameter sockp is
a socket; if it is RPCANYSOCK, then this routine opens
a new one and sets sockp. Since TCP-based RPC uses
buffered I/O , the user may specify the size of the
send and receive buffers with the parameters sendsz and
recvsz; values of zero choose suitable defaults. This
routine returns NULL if it fails.
CLIENT *
clntudpcreate(addr, pronum, versnum, wait, sockp)
struct sockaddrin *addr;
ulong prognum, versnum;
struct timeval wait;
int *sockp;
This routine creates an RPC client for the remote
program prognum, version versnum; the client uses use
UDP/IP as a transport. The remote program is located at
Internet address addr. If addr->sinport is zero, then
it is set to actual port that the remote program is
listening on (the remote portmap service is consulted
for this information). The parameter sockp is a socket;
if it is RPCANYSOCK, then this routine opens a new one
and sets sockp. The UDP transport resends the call
message in intervals of wait time until a response is
Licensed material--property of copyright holder(s) Page 8
rpc(3N) DG/UX 4.30 rpc(3N)
received or until the call times out. The total time
for the call to time out is specified by clntcall().
Warning: since UDP-based RPC messages can only hold up
to 8 Kbytes of encoded data, this transport cannot be
used for procedures that take large arguments or return
huge results.
host2netname(name, host, domain)
char *name;
char *host;
char *domain;
Convert from a domain-specific hostname to an
operating-system independent netname. Return TRUE if it
succeeds and FALSE if it fails. Inverse of
netname2host().
keydecryptsession(remotename, deskey)
char *remotename;
desblock *deskey;
keydecryptsession() is an interface to the keyserver
daemon, which is associated with RPC's secure
authentication system (DES authentication). User
programs rarely need to call it, or its associated
routines keyencryptsession(), keygendes() and
keysetsecret(). System commands such as login and the
RPC library are the main clients of these four
routines.
keydecryptsession() takes a server netname and a des
key, and decrypts the key by using the the public key
of the the server and the secret key associated with
the effective uid of the calling process. It is the
inverse of keyencryptsession().
keyencryptsession(remotename, deskey)
char *remotename;
desblock *deskey;
keyencryptsession() is a keyserver interface routine.
It takes a server netname and a des key, and encrypts
it using the public key of the the server and the
secret key associated with the effective uid of the
calling process. It is the inverse of
keydecryptsession().
keygendes(deskey)
desblock *deskey;
keygendes() is a keyserver interface routine. It is
Licensed material--property of copyright holder(s) Page 9
rpc(3N) DG/UX 4.30 rpc(3N)
used to ask the keyserver for a secure conversation
key. Choosing one at random is usually not good
enough, because the common ways of choosing random
numbers, such as using the current time, are very easy
to guess.
keysetsecret(key)
char *key;
keysetsecret() is a keyserver interface routine. It is
used to set the key for the effective uid of the
calling process.
void
getmyaddress(addr)
struct sockaddrin *addr;
Stuff the machine's IP address into *addr, without
consulting the library routines that deal with
/etc/hosts. The port number is always set to
htons(PMAPPORT).
getnetname(name)
char name[MAXNETNAMELEN];
getnetname() installs the unique, operating-system
independent netname of the caller in the fixed-length
array name. Returns TRUE if it succeeds and FALSE if
it fails.
netname2host(name, host, hostlen)
char *name;
char *host;
int hostlen;
Convert from an operating-system independent netname to
a domain-specific hostname. Returns TRUE if it succeeds
and FALSE if it fails. Inverse of host2netname().
netname2user(name, uidp, gidp, gidlenp, gidlist)
char *name;
int *uidp;
int *gidp;
int *gidlenp;
int *gidlist;
Convert from an operating-system independent netname to
a domain-specific user ID. Returns TRUE if it succeeds
and FALSE if it fails. Inverse of user2netname().
struct pmaplist *
pmapgetmaps(addr)
Licensed material--property of copyright holder(s) Page 10
rpc(3N) DG/UX 4.30 rpc(3N)
struct sockaddrin *addr;
A user interface to the portmap service, which returns
a list of the current RPC program-to-port mappings on
the host located at IP address *addr. This routine can
return NULL . The command `rpcinfo -p' uses this
routine.
ushort
pmapgetport(addr, prognum, versnum, protocol)
struct sockaddrin *addr;
ulong prognum, versnum, protocol;
A user interface to the portmap service, which returns
the port number on which waits a service that supports
program number prognum, version versnum, and speaks the
transport protocol associated with protocol. The value
of protocol is most likely IPPROTOUDP or IPPROTOTCP.
A return value of zero means that the mapping does not
exist or that the RPC system failured to contact the
remote portmap service. In the latter case, the global
variable rpccreateerr() contains the RPC status.
enum clntstat
pmaprmtcall(addr, prognum, versnum, procnum, inproc, in, outproc,
out, tout, portp)
struct sockaddrin *addr;
ulong prognum, versnum, procnum;
char *in, *out;
xdrproct inproc, outproc;
struct timeval tout;
ulong *portp;
A user interface to the portmap service, which
instructs portmap on the host at IP address *addr to
make an RPC call on your behalf to a procedure on that
host. The parameter *portp will be modified to the
program's port number if the procedure succeeds. The
definitions of other parameters are discussed in
callrpc() and clntcall(). This procedure should be
used for a ping and nothing else. See also
clntbroadcast().
pmapset(prognum, versnum, protocol, port)
ulong prognum, versnum, protocol;
ushort port;
A user interface to the portmap service, which
establishes a mapping between the triple
[prognum,versnum,protocol] and port on the machine's
portmap service. The value of protocol is most likely
IPPROTOUDP or IPPROTOTCP. This routine returns one
Licensed material--property of copyright holder(s) Page 11
rpc(3N) DG/UX 4.30 rpc(3N)
if it succeeds, zero otherwise. Automatically done by
svcregister().
pmapunset(prognum, versnum)
ulong prognum, versnum;
A user interface to the portmap service, which destroys
all mapping between the triple [prognum,versnum,*] and
ports on the machine's portmap service. This routine
returns one if it succeeds, zero otherwise.
registerrpc(prognum, versnum, procnum, procname, inproc, outproc)
ulong prognum, versnum, procnum;
char *(*procname) () ;
xdrproct inproc, outproc;
Register procedure procname with the RPC service
package. If a request arrives for program prognum,
version versnum, and procedure procnum, procname is
called with a pointer to its parameter(s); progname
should return a pointer to its static result(s); inproc
is used to decode the parameters while outproc is used
to encode the results. This routine returns zero if
the registration succeeded, -1 otherwise.
Warning: remote procedures registered in this form are
accessed using the UDP/IP transport; see
svcudpcreate() for restrictions.
struct rpccreateerr rpccreateerr;
A global variable whose value is set by any RPC client
creation routine that does not succeed. Use the
routine clntpcreateerror() to print the reason why.
svcdestroy(xprt)
SVCXPRT *xprt;
A macro that destroys the RPC service transport handle,
xprt. Destruction usually involves deallocation of
private data structures, including xprt itself. Use of
xprt is undefined after calling this routine.
fdset svcfdset;
A global variable reflecting the RPC service side's
read file descriptor bit mask; it is suitable as a
parameter to the select system call. This is only of
interest if a service implementor does not call
svcrun(), but rather does his own asynchronous event
processing. This variable is read-only (do not pass
its address to select!), yet it may change after calls
Licensed material--property of copyright holder(s) Page 12
rpc(3N) DG/UX 4.30 rpc(3N)
to svcgetreqset() or any creation routines.
int svcfds;
Similar to svcfedset(), but limited to 32 descriptors.
This interface is obsoleted by svcfdset().
svcfreeargs(xprt, inproc, in)
SVCXPRT *xprt;
xdrproct inproc;
char *in;
A macro that frees any data allocated by the RPC/XDR
system when it decoded the arguments to a service
procedure using svcgetargs(). This routine returns 1
if the results were successfully freed, and zero
otherwise.
svcgetargs(xprt, inproc, in)
SVCXPRT *xprt;
xdrproct inproc;
char *in;
A macro that decodes the arguments of an RPC request
associated with the RPC service transport handle, xprt.
The parameter in is the address where the arguments
will be placed; inproc is the XDR routine used to
decode the arguments. This routine returns one if
decoding succeeds, and zero otherwise.
struct sockaddrin *
svcgetcaller(xprt)
SVCXPRT *xprt;
The approved way of getting the network address of the
caller of a procedure associated with the RPC service
transport handle, xprt.
svcgetreqset(rdfds)
fdset *rdfds;
This routine is only of interest if a service
implementor does not call svcrun(), but instead
implements custom asynchronous event processing. It is
called when the select system call has determined that
an RPC request has arrived on some RPC socket(s) ;
rdfds is the resultant read file descriptor bit mask.
The routine returns when all sockets associated with
the value of rdfds have been serviced.
svcgetreq(rdfds)
int rdfds;
Licensed material--property of copyright holder(s) Page 13
rpc(3N) DG/UX 4.30 rpc(3N)
Similar to svcgetreqset(), but limited to 32
descriptors. This interface is obsoleted by
svcgetreqset().
svcregister(xprt, prognum, versnum, dispatch, protocol)
SVCXPRT *xprt;
ulong prognum, versnum;
void (*dispatch) ();
ulong protocol;
Associates prognum and versnum with the service
dispatch procedure, dispatch. If protocol is zero, the
service is not registered with the portmap service. If
protocol is non-zero, then a mapping of the triple
[prognum,versnum,protocol] to xprt->xpport is
established with the local portmap service (generally
protocol is zero, IPPROTOUDP or IPPROTOTCP ). The
procedure dispatch has the following form:
dispatch(request, xprt)
struct svcreq *request;
SVCXPRT *xprt;
The svcregister() routine returns one if it succeeds,
and zero otherwise.
svcrun()
This routine never returns. It waits for RPC requests
to arrive, and calls the appropriate service procedure
using svcgetreq() when one arrives. This procedure is
usually waiting for a select() system call to return.
svcsendreply(xprt, outproc, out)
SVCXPRT *xprt;
xdrproct outproc;
char *out;
Called by an RPC service's dispatch routine to send the
results of a remote procedure call. The parameter xprt
is the request's associated transport handle; outproc
is the XDR routine which is used to encode the results;
and out is the address of the results. This routine
returns one if it succeeds, zero otherwise.
void
svcunregister(prognum, versnum)
ulong prognum, versnum;
Remove all mapping of the double [prognum,versnum] to
dispatch routines, and of the triple
[prognum,versnum,*] to port number.
Licensed material--property of copyright holder(s) Page 14
rpc(3N) DG/UX 4.30 rpc(3N)
void
svcerrauth(xprt, why)
SVCXPRT *xprt;
enum authstat why;
Called by a service dispatch routine that refuses to
perform a remote procedure call due to an
authentication error.
void
svcerrdecode(xprt)
SVCXPRT *xprt;
Called by a service dispatch routine that cannot
successfully decode its parameters. See also
svcgetargs().
void
svcerrnoproc(xprt)
SVCXPRT *xprt;
Called by a service dispatch routine that does not
implement the procedure number that the caller
requests.
void
svcerrnoprog(xprt)
SVCXPRT *xprt;
Called when the desired program is not registered with
the RPC package. Service implementors usually do not
need this routine.
void
svcerrprogvers(xprt)
SVCXPRT *xprt;
Called when the desired version of a program is not
registered with the RPC package. Service implementors
usually do not need this routine.
void
svcerrsystemerr(xprt)
SVCXPRT *xprt;
Called by a service dispatch routine when it detects a
system error not covered by any particular protocol.
For example, if a service can no longer allocate
storage, it may call this routine.
void
svcerrweakauth(xprt)
Licensed material--property of copyright holder(s) Page 15
rpc(3N) DG/UX 4.30 rpc(3N)
SVCXPRT *xprt;
Called by a service dispatch routine that refuses to
perform a remote procedure call due to insufficient
(but correct) authentication parameters. The routine
calls svcerrauth(xprt, AUTHTOOWEAK).
SVCXPRT *
svcrawcreate()
This routine creates a toy RPC service transport, to
which it returns a pointer. The transport is really a
buffer within the process's address space, so the
corresponding RPC client should live in the same
address space; see clntrawcreate(). This routine
allows simulation of RPC and acquisition of RPC
overheads (such as round trip times), without any
kernel interference. This routine returns NULL if it
fails.
SVCXPRT *
svctcpcreate(sock, sendbufsize, recvbufsize)
int sock;
uint sendbufsize, recvbufsize;
This routine creates a TCP/IP-based RPC service
transport, to which it returns a pointer. The
transport is associated with the socket sock, which may
be RPCANYSOCK, in which case a new socket is created.
If the socket is not bound to a local TCP port, then
this routine binds it to an arbitrary port. Upon
completion, xprt->xpsock is the transport's socket
descriptor, nd xprt->xpport is the transport's port
number. This routine returns NULL if it fails. Since
TCP-based RPC uses buffered I/O , users may specify the
size of buffers; values of zero choose suitable
defaults.
void
svcfdcreate(fd, sendsize, recvsize)
int fd;
uint sendsize;
uint recvsize;
Create a service on top of any open desciptor.
Typically, this descriptor is a connected socket for a
stream protocol such as TCP. sendsize and recvsize
indicate sizes for the send and receive buffers. If
they are zero, a reasonable default is chosen.
SVCXPRT *
svcudpcreate(sock)
Licensed material--property of copyright holder(s) Page 16
rpc(3N) DG/UX 4.30 rpc(3N)
int sock;
This routine creates a UDP/IP-based RPC service
transport, to which it returns a pointer. The
transport is associated with the socket sock, which may
be RPCANYSOCK , in which case a new socket is created.
If the socket is not bound to a local UDP port, then
this routine binds it to an arbitrary port. Upon
completion, xprt->xpsock is the transport's socket
descriptor, and xprt->xpport is the transport's port
number. This routine returns NULL if it fails.
Warning: since UDP-based RPC messages can only hold up
to 8 Kbytes of encoded data, this transport cannot be
used for procedures that take large arguments or return
huge results.
user2netname(name, uid, domain)
char *name;
int uid;
char *domain;
Convert from a domain-specific username to an
operating-system independent netname. Returns TRUE if
it succeeds and FALSE if it fails. Inverse of
netname2user().
xdracceptedreply(xdrs, ar)
XDR *xdrs;
struct acceptedreply *ar;
Used for encoding RPC reply messages. This routine is
useful for users who wish to generate RPC-style
messages without using the RPC package.
xdrauthunixparms(xdrs, aupp)
XDR *xdrs;
struct authunixparms *aupp;
Used for describing UNIX credentials. This routine is
useful for users who wish to generate these credentials
without using the RPC authentication package.
void
xdrcallhdr(xdrs, chdr)
XDR *xdrs;
struct rpcmsg *chdr;
Used for describing RPC call header messages. This
routine is useful for users who wish to generate RPC-
style messages without using the RPC package.

xdrcallmsg(xdrs, cmsg)
XDR *xdrs;
struct rpcmsg *cmsg;
Used for describing RPC call messages. This routine is
useful for users who wish to generate RPC-style
messages without using the RPC package.
xdropaqueauth(xdrs, ap)
XDR *xdrs;
struct opaqueauth *ap;
Used for describing RPC authentication information
messages. This routine is useful for users who wish to
generate RPC-style messages without using the RPC
package.
xdrpmap(xdrs, regs)
XDR *xdrs;
struct pmap *regs;
Used for describing parameters to various portmap
procedures, externally. This routine is useful for
users who wish to generate these parameters without
using the pmap interface.
xdrpmaplist(xdrs, rp)
XDR *xdrs;
struct pmaplist **rp;
Used for describing a list of port mappings,
externally. This routine is useful for users who wish
to generate these parameters without using the pmap
interface.
xdrrejectedreply(xdrs, rr)
XDR *xdrs;
struct rejectedreply *rr;
Used for describing RPC reply messages. This routine
is useful for users who wish to generate RPC-style
messages without using the RPC package.
xdrreplymsg(xdrs, rmsg)
XDR *xdrs;
struct rpcmsg *rmsg;
Used for describing RPC reply messages. This routine
is useful for users who wish to generate RPC style
messages without using the RPC package.

xprtregister(xprt)
SVCXPRT *xprt;
After RPC service transport handles are created, they
should register themselves with the RPC service
package. This routine modifies the global variable
svcfds(). Service implementors usually do not need
this routine.
void
xprtunregister(xprt)
SVCXPRT *xprt;
Before an RPC service transport handle is destroyed, it
should unregister itself with the RPC service package.
This routine modifies the global variable svcfds().
Service implementors usually do not need this routine.
