LIBRARY¶
Standard C Library (libc, -lc)
SYNOPSIS¶
#include <rpc/rpc.h>
See
DESCRIPTION for function declarations.
DESCRIPTION¶
The
svc_*() and
clnt_*() functions described
in this page are the old, TS-RPC interface to the XDR and RPC library, and
exist for backward compatibility. The new interface is described in the pages
referenced from
rpc(3).
These routines allow C programs to 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.
Routines that are used for Secure RPC (DES authentication) are described in
rpc_secure(3). Secure RPC can be used only if DES encryption
is available.
- void
-
- auth_destroy(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 return an RPC authentication handle that passes nonusable
authentication information with each remote procedure call. This is the
default authentication used by RPC.
- AUTH
*
-
- authunix_create(char
*host, int uid, int gid,
int len, int *aup_gids)
-
Create and return an RPC authentication handle that contains
UNIX authentication information. The
host argument 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 arguments.
- int
callrpc(char *host,
u_long prognum, u_long versnum,
u_long procnum, xdrproc_t
inproc, void *in, xdrproc_t
outproc, void *out);
-
Call the remote procedure associated with prognum,
versnum, and procnum on the
machine host. The in argument
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 arguments,
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(u_long
prognum, u_long versnum, u_long
procnum, xdrproc_t inproc, char
*in, xdrproc_t outproc, char
*out, bool_t (*eachresult)(caddr_t, struct sockaddr_in
*));
-
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:
bool_t
eachresult(caddr_t 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(CLIENT
*clnt, u_long procnum, xdrproc_t
inproc, char *in, xdrproc_t
outproc, char *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 in argument 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 arguments,
and outproc is used to decode the procedure's
results; tout is the time allowed for results to
come back.
- void
clnt_destroy(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(char
*host, u_long prog, u_long
vers, char *proto)
-
Generic client creation routine. The host argument
identifies the name of the remote host where the server is located. The
proto argument 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(CLIENT
*cl, u_int req, char
*info)
-
A macro used to change or retrieve various information about a client
object. The req argument 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 argument passed to clnt_call() will be ignored
in all future calls.
CLGET_SERVER_ADDR |
struct sockaddr_in |
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.
- bool_t
clnt_freeres(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 out argument 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(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(char
*s)
-
prints 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. A newline is appended at the end of
the message. Used when a clnt_create(),
clntraw_create(), clnttcp_create(), or
clntudp_create() call fails.
- void
-
- clnt_perrno(enum
clnt_stat stat)
-
Print a message to standard error corresponding to the condition indicated
by stat. A newline is appended at the end of the
message. Used after callrpc().
- void
clnt_perror(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. A newline is
appended at the end of the message. 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(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 clnt_sperrno() function 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 from that
supported by clnt_perrno() is to be used.
Note: unlike clnt_sperror() and
clnt_spcreateerror(), clnt_sperrno()
returns pointer to static data, but the result will not get overwritten on
each call.
- char
*
-
- clnt_sperror(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(u_long
prognum, u_long 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(struct
sockaddr_in *addr, u_long prognum,
u_long versnum, int *sockp,
u_int sendsz, u_int
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
rpcbind(8) service is consulted for this information).
The sockp argument 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
sendsz and recvsz arguments;
values of zero choose suitable defaults. This routine returns
NULL
if it fails.
- CLIENT
*
-
- clntudp_create(struct
sockaddr_in *addr, u_long prognum,
u_long versnum, struct timeval
wait, int *sockp);
-
This routine creates an RPC client for the remote program
prognum, version versnum; the
client uses 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
rpcbind(8) service is consulted for this information).
The sockp argument 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.
- CLIENT
*
-
- clntudp_bufcreate(struct
sockaddr_in *addr, u_long prognum,
u_long versnum, struct timeval
wait, int *sockp, unsigned int
sendsize, unsigned int recosize);
-
This routine creates an RPC client for the remote program
prognum, on versnum; the
client uses 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
rpcbind(8) service is consulted for this information).
The sockp argument 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().
This allows the user to specify the maximum packet size for sending and
receiving UDP-based RPC messages.
- CLIENT
*
-
- clntunix_create(struct
sockaddr_un *raddr, u_long prognum,
u_long versnum, int *sockp,
u_int sendsz, u_int
recvsz);
-
This routine creates an RPC client for the local program
prognum, version versnum; the
client uses UNIX-domain sockets as a transport.
The local program is located at the *raddr. The
sockp argument is a socket; if it is
RPC_ANYSOCK
, then this routine opens a new one and
sets sockp. Since UNIX-based
RPC uses buffered I/O, the user may specify the size of the send and
receive buffers with the sendsz and
recvsz arguments; values of zero choose suitable
defaults. This routine returns NULL
if it fails.
- int
-
- get_myaddress(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). Returns zero on
success, non-zero on failure.
- struct
pmaplist *
-
- pmap_getmaps(struct
sockaddr_in *addr)
-
A user interface to the rpcbind(8) 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(struct
sockaddr_in *addr, u_long prognum,
u_long versnum, u_long
protocol);
-
A user interface to the rpcbind(8) 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 failed to contact the remote
rpcbind(8) service. In the latter case, the global
variable rpc_createerr contains the RPC status.
- enum
clnt_stat
-
- pmap_rmtcall(struct
sockaddr_in *addr, u_long prognum,
u_long versnum, u_long procnum,
xdrproc_t inproc, char *in,
xdrproc_t outproc, char *out,
struct timeval tout, u_long
*portp);
-
A user interface to the rpcbind(8) service, which
instructs rpcbind(8) on the host at IP address
addr to make an RPC call on your behalf to a
procedure on that host. The portp argument will be
modified to the program's port number if the procedure succeeds. The
definitions of other arguments are discussed in
callrpc() and clnt_call(). This
procedure should be used for a “ping” and nothing else. See
also clnt_broadcast().
- bool_t
pmap_set(u_long prognum,
u_long versnum, u_long protocol,
u_short port)
-
A user interface to the rpcbind(8) service, which
establishes a mapping between the triple (prognum,
versnum, protocol) and
port on the machine's rpcbind(8)
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().
- bool_t
pmap_unset(u_long prognum,
u_long versnum)
-
A user interface to the rpcbind(8) service, which destroys
all mapping between the triple (prognum,
versnum, *) and
ports on the machine's rpcbind(8)
service. This routine returns one if it succeeds, zero otherwise.
- bool_t
registerrpc(u_long prognum,
u_long versnum, u_long procnum,
char *(*procname)(void), xdrproc_t
inproc, xdrproc_t 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 argument(s); progname should
return a pointer to its static result(s); inproc is
used to decode the arguments 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 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.
- bool_t
svc_destroy(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 template argument to the
select(2) 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(2)!), yet it may change
after calls to svc_getreqset() or any creation routines.
As well, note that if the process has descriptor limits which are extended
beyond
FD_SETSIZE
, this variable will only be
usable for the first FD_SETSIZE
descriptors.
- int
svc_fds;
-
Similar to svc_fdset, but limited to 32 descriptors.
This interface is obsoleted by svc_fdset.
- bool_t
svc_freeargs(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.
- bool_t
svc_getargs(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
in argument 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
sockaddr_in *
-
- svc_getcaller(SVCXPRT
*xprt)
-
The approved way of getting the network address of the caller of a procedure
associated with the RPC service transport handle,
xprt.
- void
svc_getreqset(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(2) 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.
- void
svc_getreq(int rdfds)
-
Similar to svc_getreqset(), but limited to 32 descriptors.
This interface is obsoleted by svc_getreqset().
- bool_t
svc_register(SVCXPRT *xprt,
u_long prognum, u_long versnum,
void (*dispatch)(struct svc_req *, SVCXPRT *),
int protocol);
-
Associates prognum and versnum
with the service dispatch procedure, dispatch(). If
protocol is zero, the service is not registered with
the rpcbind(8) service. If
protocol is non-zero, then a mapping of the triple
(prognum, versnum,
protocol) to xprt->xp_port
is established with the local rpcbind(8) service
(generally protocol is zero,
IPPROTO_UDP
or
IPPROTO_TCP
). The procedure
dispatch() has the following form:
bool_t
dispatch(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(2) system call to return.
- bool_t
svc_sendreply(SVCXPRT *xprt,
xdrproc_t outproc, char
*out)
-
Called by an RPC service's dispatch routine to send the results of a remote
procedure call. The xprt argument 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(u_long
prognum, u_long versnum)
-
Remove all mapping of the double (prognum,
versnum) to dispatch routines, and of the triple
(prognum, versnum,
*) to port number.
- void
-
- svcerr_auth(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(SVCXPRT
*xprt)
-
Called by a service dispatch routine that cannot successfully decode its
arguments. See also svc_getargs().
- void
-
- svcerr_noproc(SVCXPRT
*xprt)
-
Called by a service dispatch routine that does not implement the procedure
number that the caller requests.
- void
-
- svcerr_noprog(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(SVCXPRT
*xprt, u_long low_vers, u_long
high_vers)
-
Called when the desired version of a program is not registered with the RPC
package. Service implementors usually do not need this routine.
- void
-
- svcerr_systemerr(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(SVCXPRT
*xprt)
-
Called by a service dispatch routine that refuses to perform a remote
procedure call due to insufficient authentication arguments. The routine
calls svcerr_auth(xprt,
AUTH_TOOWEAK).
- SVCXPRT
*
-
- svcraw_create(void)
-
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(int
sock, u_int send_buf_size, u_int
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_fd is the transport's socket descriptor,
and 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.
- SVCXPRT
*
-
- svcunix_create(int
sock, u_int send_buf_size, u_int
recv_buf_size, char *path)
-
This routine creates a UNIX-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. The *path argument is a variable-length
file system pathname of at most 104 characters. This file is
not removed when the socket is closed. The
unlink(2) system call must be used to remove the file.
Upon completion, xprt->xp_fd is the transport's
socket descriptor. This routine returns NULL
if it
fails. Since UNIX-based RPC uses buffered I/O,
users may specify the size of buffers; values of zero choose suitable
defaults.
- SVCXPRT
*
-
- svcunixfd_create(int
fd, u_int sendsize, u_int
recvsize)
-
Create a service on top of any open descriptor. The
sendsize and recvsize
arguments indicate sizes for the send and receive buffers. If they are
zero, a reasonable default is chosen.
- SVCXPRT
*
-
- svcfd_create(int
fd, u_int sendsize, u_int
recvsize)
-
Create a service on top of any open descriptor. Typically, this descriptor
is a connected socket for a stream protocol such as TCP. The
sendsize and recvsize
arguments indicate sizes for the send and receive buffers. If they are
zero, a reasonable default is chosen.
- SVCXPRT
*
-
- svcudp_bufcreate(int
sock, u_int sendsize, u_int
recvsize)
-
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_fd is the transport's socket descriptor,
and xprt->xp_port is the transport's port number.
This routine returns NULL
if it fails.
This allows the user to specify the maximum packet size for sending and
receiving UDP-based RPC messages.
- bool_t
xdr_accepted_reply(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.
- bool_t
xdr_authunix_parms(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
-
- bool_t
xdr_callhdr(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.
- bool_t
xdr_callmsg(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.
- bool_t
xdr_opaque_auth(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.

pmap;
-
- bool_t
xdr_pmap(XDR *xdrs,
struct pmap *regs)
-
Used for describing arguments to various rpcbind(8)
procedures, externally. This routine is useful for users who wish to
generate these arguments without using the pmap_*()
interface.
- bool_t
xdr_pmaplist(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 arguments without using the
pmap_*() interface.
- bool_t
xdr_rejected_reply(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.
- bool_t
xdr_replymsg(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(SVCXPRT
*xprt)
-
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(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.
