procedure calls
SYNOPSIS 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
auth_destroy(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 auth_destroy().
AUTH *
authnone_create()
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.
AUTH *
authdes_create(name, window, syncaddr, ckey)
char *name;
unsigned window;
struct sockaddr *syncaddr;
des_block *ckey;

NOTE: Secure RPC using DES Authentication is an additional feature
that must be purchased separately from the DG/UX (Trademark) ONC
(Trademark)/NFS® product.
authdes_create() is the first of two routines which interface
to the RPC secure authentication system, known as DES
authentication. The second is authdes_getucred(), below.
Note: the keyserver daemon keyserv(1M) must be running for the
DES authentication system to work.
authdes_create(), 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.
authdes_getucred(adc, uid, gid, grouplen, groups)
struct authdes_cred *adc;
short *uid;
short *gid;
short *grouplen;
int *groups;
authdes_getucred(), the second of the two DES authentication
routines, is used on the server side for converting a DES
credential, which is operating system independent, into a UNIX
credential. This routine differs from utility routine
netname2user in that authdes_getucred() pulls its information
from a cache, and does not have to do a Network Information
Services (NIS) lookup everytime it is called to get its
information.
AUTH *
authunix_create(host, uid, gid, len, aup_gids)
char *host;
int uid, gid, len, *aup.gids;
Licensed material--property of copyright holder(s) 2
rpc(3N) DG/UX 5.4.2 rpc(3N)
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 *
authunix_create_default()
Calls authunix_create() with the appropriate parameters.
callrpc(host, prognum, versnum, procnum, inproc, in, outproc, out)
char *host;
u_long prognum, versnum, procnum;
char *in, *out;
xdrproc_t 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 clnt_stat cast to an integer if
it fails. The routine clnt_perrno() is handy for translating
failure statuses into messages.
Warning: calling remote procedures with this routine uses
UDP/IP as a transport; see clntudp_create() for restrictions.
You do not have control of timeouts or authentication using
this routine.
enum clnt_stat
clnt_broadcast(prognum, versnum, procnum, inproc, in, outproc,
out, eachresult)
u_long prognum, versnum, procnum;
char *in, *out;
xdrproc_t inproc, outproc;
resultproc_t 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 sockaddr_in *addr;
where out is the same as out passed to clnt_broadcast(),
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, clnt_broadcast() 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 clnt_stat
clnt_call(clnt, procnum, inproc, in, outproc, out, tout)
CLIENT *clnt;
u_long
procnum;
xdrproc_t 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 clnt_create(). 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.
clnt_destroy(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
clnt_destroy(). If the RPC library opened the associated
socket, it will close it also. Otherwise, the socket remains
open.
CLIENT *
clnt_create(host, prog, vers, proto)
char *host;
u_long 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 clnt_control().
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.
bool_t
clnt_control(cl, req, info)
CLIENT *cl;
Licensed material--property of copyright holder(s) 4
rpc(3N) DG/UX 5.4.2 rpc(3N)
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 clnt_control(), the timeout
parameter passed to clnt_call() will be ignored in all future
calls.
CLGET_SERVER_ADDR struct sockaddr get server's address
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.
clnt_freeres(clnt, outproc, out)
CLIENT *clnt;
xdrproc_t 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
clnt_geterr(clnt, errp)
CLIENT *clnt;
struct rpc_err *errp;
A macro that copies the error structure out of the client
handle to the structure at address errp.
void
clnt_pcreateerror(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 clnt_create(),
clntraw_create(), clnttcp_create(), or clntudp_create() call
fails.
Licensed material--property of copyright holder(s) 5
rpc(3N) DG/UX 5.4.2 rpc(3N)
void
clnt_perrno(stat)
enum clnt_stat stat;
Print a message to standard error corresponding to the
condition indicated by stat. Used after callrpc().
clnt_perror(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
clnt_call().
char *
clnt_spcreateerror
char *s;
Like clnt_pcreateerror(), 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 *
clnt_sperrno(stat)
enum clnt_stat stat;
Take the same arguments as clnt_perrno(), 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.
clnt_sperrno() is used instead of clnt_perrno() 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 clnt_perrno() is to be
used. Note: unlike clnt_sperror() and clnt_spcreaterror(),
clnt_sperrno() does not return pointer to static data so the
result will not get overwritten on each call.
char *
clnt_sperror(rpch, s)
CLIENT *rpch;
char *s;
Like clnt_perror(), except that (like clnt_sperrno()) it
returns a string instead of printing to standard error.
Bugs: returns pointer to static data that is overwritten on
each call.

CLIENT *
clntraw_create(prognum, versnum)
u_long 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 svcraw_create(). 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 *
clnttcp_create(addr, prognum, versnum, sockp, sendsz, recvsz)
struct sockaddr_in *addr;
u_long prognum, versnum;
int *sockp;
u_int 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->sin_port 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 RPC_ANYSOCK, 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 *
clntudp_create(addr, pronum, versnum, wait, sockp)
struct sockaddr_in *addr;
u_long 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->sin_port 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 RPC_ANYSOCK, 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 received or until the call times out. The total
time for the call to time out is specified by clnt_call().
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().
key_decryptsession(remotename, deskey)
char *remotename;
des_block *deskey;
key_decryptsession() 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 key_encryptsession(), key_gendes()
and key_setsecret(). System commands such as login and the
RPC library are the main clients of these four routines.
key_decryptsession() 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 key_encryptsession().
key_encryptsession(remotename, deskey)
char *remotename;
des_block *deskey;
key_encryptsession() 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 key_decryptsession().
key_gendes(deskey)
des_block *deskey;
key_gendes() is a keyserver interface routine. It is 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.
key_setsecret(key)
char *key;
key_setsecret() is a keyserver interface routine. It is used
to set the key for the effective uid of the calling process.
void
get_myaddress(addr)
Licensed material--property of copyright holder(s) 8
rpc(3N) DG/UX 5.4.2 rpc(3N)
struct sockaddr_in *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 *
pmap_getmaps(addr)
struct sockaddr_in *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.
u_short
pmap_getport(addr, prognum, versnum, protocol)
struct sockaddr_in *addr;
u_long 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 IPPROTO_UDP or IPPROTO_TCP. 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
Licensed material--property of copyright holder(s) 9
rpc(3N) DG/UX 5.4.2 rpc(3N)
latter case, the global variable rpc_createerr() contains the
RPC status.
enum clnt_stat
pmap_rmtcall(addr, prognum, versnum, procnum, inproc, in, outproc,
out, tout, portp)
struct sockaddr_in *addr;
u_long prognum, versnum, procnum;
char *in, *out;
xdrproc_t inproc, outproc;
struct timeval tout;
u_long *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 clnt_call(). This procedure should be used for
a "ping" and nothing else. See also clnt_broadcast().
pmap_set(prognum, versnum, protocol, port)
u_long prognum, versnum, protocol;
u_short 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 IPPROTO_UDP or IPPROTO_TCP. This routine returns
one if it succeeds, zero otherwise. Automatically done by
svc_register().
pmap_unset(prognum, versnum)
u_long 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)
u_long prognum, versnum, procnum;
char *(*procname) () ;
xdrproc_t 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
Licensed material--property of copyright holder(s) 10

accessed using the UDP/IP transport; see svcudp_create() for
restrictions.
struct rpc_createerr rpc_createerr;
A global variable whose value is set by any RPC client
creation routine that does not succeed. Use the routine
clnt_pcreateerror() to print the reason why.
svc_destroy(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.
fd_set svc_fdset;
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 svc_run(), 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 to svc_getreqset() or any creation routines.
int svc_fds;
Similar to svc_fedset(), but limited to 32 descriptors. This
interface is obsoleted by svc_fdset().
svc_freeargs(xprt, inproc, in)
SVCXPRT *xprt;
xdrproc_t 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
svc_getargs(). This routine returns 1 if the results were
successfully freed, and zero otherwise.
svc_getargs(xprt, inproc, in)
SVCXPRT *xprt;
xdrproc_t 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.
Licensed material--property of copyright holder(s) 11
rpc(3N) DG/UX 5.4.2 rpc(3N)
struct sockaddr_in *
svc_getcaller(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.
svc_getreqset(rdfds)
fd_set *rdfds;
This routine is only of interest if a service implementor does
not call svc_run(), 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.
svc_getreq(rdfds)
int rdfds;
Similar to svc_getreqset(), but limited to 32 descriptors.
This interface is obsoleted by svc_getreqset().
svc_register(xprt, prognum, versnum, dispatch, protocol)
SVCXPRT *xprt;
u_long prognum, versnum;
void (*dispatch) ();
u_long 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->xp_port is established with the local portmap service
(generally protocol is zero, IPPROTO_UDP or IPPROTO_TCP ).
The procedure dispatch has the following form:
dispatch(request, xprt)
struct svc_req *request;
SVCXPRT *xprt;
The svc_register() routine returns one if it succeeds, and
zero otherwise.
svc_run()
This routine never returns. It waits for RPC requests to
arrive, and calls the appropriate service procedure using
svc_getreq() when one arrives. This procedure is usually
waiting for a select() system call to return.
svc_sendreply(xprt, outproc, out)
SVCXPRT *xprt;
Licensed material--property of copyright holder(s) 12
rpc(3N) DG/UX 5.4.2 rpc(3N)
xdrproc_t 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
svc_unregister(prognum, versnum)
u_long prognum, versnum;
Remove all mapping of the double [prognum,versnum] to dispatch
routines, and of the triple [prognum,versnum,*] to port
number.
void
svcerr_auth(xprt, why)
SVCXPRT *xprt;
enum auth_stat why;
Called by a service dispatch routine that refuses to perform a
remote procedure call due to an authentication error.
void
svcerr_decode(xprt)
SVCXPRT *xprt;
Called by a service dispatch routine that cannot successfully
decode its parameters. See also svc_getargs().
void
svcerr_noproc(xprt)
SVCXPRT *xprt;
Called by a service dispatch routine that does not implement
the procedure number that the caller requests.
void
svcerr_noprog(xprt)
SVCXPRT *xprt;
Called when the desired program is not registered with the RPC
package. Service implementors usually do not need this
routine.
void
svcerr_progvers(xprt)
SVCXPRT *xprt;
Called when the desired version of a program is not registered
with the RPC package. Service implementors usually do not need
Licensed material--property of copyright holder(s) 13

this routine.
void
svcerr_systemerr(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
svcerr_weakauth(xprt)
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
svcerr_auth(xprt, AUTH_TOOWEAK).
SVCXPRT *
svcraw_create()
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 clntraw_create().
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 *
svctcp_create(sock, send_buf_size, recv_buf_size)
int sock;
u_int send_buf_size, recv_buf_size;
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 RPC_ANYSOCK, 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->xp_sock is the transport's socket
descriptor, nd xprt->xp_port 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
svcfd_create(fd, sendsize, recvsize)
int fd;
u_int sendsize;
u_int recvsize;
Create a service on top of any open desciptor. Typically, this
Licensed material--property of copyright holder(s) 14
rpc(3N) DG/UX 5.4.2 rpc(3N)
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 *
svcudp_create(sock)
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 RPC_ANYSOCK , 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->xp_sock is the transport's socket
descriptor, and xprt->xp_port 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().
xdr_accepted_reply(xdrs, ar)
XDR *xdrs;
struct accepted_reply *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.
xdr_authunix_parms(xdrs, aupp)
XDR *xdrs;
struct authunix_parms *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
xdr_callhdr(xdrs, chdr)
XDR *xdrs;
struct rpc_msg *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.
xdr_callmsg(xdrs, cmsg)
XDR *xdrs;
struct rpc_msg *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.
xdr_opaque_auth(xdrs, ap)
XDR *xdrs;
struct opaque_auth *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.
xdr_pmap(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.
xdr_pmaplist(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.
xdr_rejected_reply(xdrs, rr)
XDR *xdrs;
struct rejected_reply *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.
xdr_replymsg(xdrs, rmsg)
XDR *xdrs;
struct rpc_msg *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.
void
xprt_register(xprt)
SVCXPRT *xprt;
Licensed material--property of copyright holder(s) 16
rpc(3N) DG/UX 5.4.2 rpc(3N)
After RPC service transport handles are created, they should
register themselves with the RPC service package. This
routine modifies the global variable svc_fds(). Service
implementors usually do not need this routine.
void
xprt_unregister(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 svc_fds(). Service implementors
usually do not need this routine.
