LIBRARY

SYNOPSIS

See Sx DESCRIPTION for function declarations.  

DESCRIPTION

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_secure3. 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 Fa auth . Destruction usually involves deallocation of private data structures. The use of Fa 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 Fa host argument is the name of the machine on which the information was created; Fa uid is the user's user ID; Fa gid is the user's current group ID; Fa len and Fa 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 Fo callrpc Fa char *host Fa u_long prognum Fa u_long versnum Fa u_long procnum Fa xdrproc_t inproc Fa void *in Fa xdrproc_t outproc Fa void *out Fc

Call the remote procedure associated with Fa prognum , Fa versnum , and Fa procnum on the machine Fa host . The Fa in argument is the address of the procedure's argument(s), and Fa out is the address of where to place the result(s); Fa inproc is used to encode the procedure's arguments, and Fa outproc is used to decode the procedure's results. This routine returns zero if it succeeds, or the value of Vt 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

Fo clnt_broadcast Fa u_long prognum Fa u_long versnum Fa u_long procnum Fa xdrproc_t inproc Fa char *in Fa xdrproc_t outproc Fa char *out Fa bool_t (*eachresult)(caddr_t, struct sockaddr_in *) Fc

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 Fa out is the same as Fa out passed to clnt_broadcast (,);
except that the remote procedure's output is decoded there; Fa 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

Fo clnt_call Fa CLIENT *clnt Fa u_long procnum Fa xdrproc_t inproc Fa char *in Fa xdrproc_t outproc Fa char *out Fa struct timeval tout Fc

A macro that calls the remote procedure Fa procnum associated with the client handle, Fa clnt , which is obtained with an RPC client creation routine such as clnt_create (.);
The Fa in argument is the address of the procedure's argument(s), and Fa out is the address of where to place the result(s); Fa inproc is used to encode the procedure's arguments, and Fa outproc is used to decode the procedure's results; Fa 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 Fa clnt itself. Use of Fa 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 Fa host argument identifies the name of the remote host where the server is located. The Fa proto argument indicates which kind of transport protocol to use. The currently supported values for this field are Qq Li udp and Qq Li 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 Fa req argument indicates the type of operation, and Fa info is a pointer to the information. For both UDP and TCP the supported values of Fa req and their argument types and what they do are:

CLSET_TIMEOUT Ta Vt struct timeval Ta set total timeout

CLGET_TIMEOUT Ta Vt struct timeval Ta 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 Ta Vt struct sockaddr_in Ta get server's address

The following operations are valid for UDP only:

CLSET_RETRY_TIMEOUT Ta Vt struct timeval Ta set the retry timeout

CLGET_RETRY_TIMEOUT Ta Vt struct timeval Ta 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 Fa out argument is the address of the results, and Fa 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 Fa 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 Fa 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 Fa 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; Fa clnt is the handle used to do the call. The message is prepended with string Fa 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 Fa prognum , version Fa 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 *

Fo clnttcp_create Fa struct sockaddr_in *addr Fa u_long prognum Fa u_long versnum Fa int *sockp Fa u_int sendsz Fa u_int recvsz Fc

This routine creates an RPC client for the remote program Fa prognum , version Fa versnum ; the client uses TCP/IP as a transport. The remote program is located at Internet address Fa addr . If Fa 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 Fa sockp argument is a socket; if it is RPC_ANYSOCK then this routine opens a new one and sets Fa sockp . Since TCP -based RPC uses buffered I/O the user may specify the size of the send and receive buffers with the Fa sendsz and Fa recvsz arguments; values of zero choose suitable defaults. This routine returns NULL if it fails.

CLIENT *

Fo clntudp_create Fa struct sockaddr_in *addr Fa u_long prognum Fa u_long versnum Fa struct timeval wait Fa int *sockp Fc

This routine creates an RPC client for the remote program Fa prognum , version Fa versnum ; the client uses UDP/IP as a transport. The remote program is located at Internet address Fa addr . If Fa 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 Fa sockp argument is a socket; if it is RPC_ANYSOCK then this routine opens a new one and sets Fa sockp . The UDP transport resends the call message in intervals of Fa 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 *

Fo clntudp_bufcreate Fa struct sockaddr_in *addr Fa u_long prognum Fa u_long versnum Fa struct timeval wait Fa int *sockp Fa unsigned int sendsize Fa unsigned int recosize Fc

This routine creates an RPC client for the remote program Fa prognum , on Fa versnum ; the client uses UDP/IP as a transport. The remote program is located at Internet address Fa addr . If Fa 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 Fa sockp argument is a socket; if it is RPC_ANYSOCK then this routine opens a new one and sets Fa sockp . The UDP transport resends the call message in intervals of Fa 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 *

Fo clntunix_create Fa struct sockaddr_un *raddr Fa u_long prognum Fa u_long versnum Fa int *sockp Fa u_int sendsz Fa u_int recvsz Fc

This routine creates an RPC client for the local program Fa prognum , version Fa versnum ; the client uses UNIX sockets as a transport. The local program is located at the Fa *raddr . The Fa sockp argument is a socket; if it is RPC_ANYSOCK then this routine opens a new one and sets Fa sockp . Since UNIX RPC uses buffered I/O the user may specify the size of the send and receive buffers with the Fa sendsz and Fa 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 Fa 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 Fa addr . This routine can return NULL The command ``rpcinfo -p '' uses this routine.

u_short

Fo pmap_getport Fa struct sockaddr_in *addr Fa u_long prognum Fa u_long versnum Fa u_long protocol Fc

A user interface to the rpcbind(8) service, which returns the port number on which waits a service that supports program number Fa prognum , version Fa versnum , and speaks the transport protocol associated with Fa protocol . The value of Fa 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

Fo pmap_rmtcall Fa struct sockaddr_in *addr Fa u_long prognum Fa u_long versnum Fa u_long procnum Fa xdrproc_t inproc Fa char *in Fa xdrproc_t outproc Fa char *out Fa struct timeval tout Fa u_long *portp Fc

A user interface to the rpcbind(8) service, which instructs rpcbind(8) on the host at IP address Fa addr to make an RPC call on your behalf to a procedure on that host. The Fa 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 (Fa prognum , versnum , protocol ) and Fa port on the machine's rpcbind(8) service. The value of Fa 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 (Fa prognum , versnum , ) and Fa ports on the machine's rpcbind(8) service. This routine returns one if it succeeds, zero otherwise.

bool_t Fo registerrpc Fa u_long prognum Fa u_long versnum Fa u_long procnum Fa char *(*procname)(void) Fa xdrproc_t inproc Fa xdrproc_t outproc Fc

Register procedure Fa procname with the RPC service package. If a request arrives for program Fa prognum , version Fa versnum , and procedure Fa procnum , Fa procname is called with a pointer to its argument(s); Fa progname should return a pointer to its static result(s); Fa inproc is used to decode the arguments while Fa 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.

Vt 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, Fa xprt . Destruction usually involves deallocation of private data structures, including Fa xprt itself. Use of Fa xprt is undefined after calling this routine.

Vt 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.

Vt 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, Fa xprt . The Fa in argument is the address where the arguments will be placed; Fa 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, Fa 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); Fa rdfds is the resultant read file descriptor bit mask. The routine returns when all sockets associated with the value of Fa 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 Fo svc_register Fa SVCXPRT *xprt Fa u_long prognum Fa u_long versnum Fa void (*dispatch)(struct svc_req *, SVCXPRT *) Fa int protocol Fc

Associates Fa prognum and Fa versnum with the service dispatch procedure, dispatch (.);
If Fa protocol is zero, the service is not registered with the rpcbind(8) service. If Fa protocol is non-zero, then a mapping of the triple (Fa prognum , versnum , protocol ) to Fa xprt->xp_port is established with the local rpcbind(8) service (generally Fa 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 Fa xprt argument is the request's associated transport handle; Fa outproc is the XDR routine which is used to encode the results; and Fa 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 (Fa prognum , versnum ) to dispatch routines, and of the triple (Fa 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 Fa 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, Fa xprt->xp_fd is the transport's socket descriptor, and Fa 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 RPC service transport, to which it returns a pointer. The transport is associated with the socket Fa sock , which may be RPC_ANYSOCK in which case a new socket is created. The Fa *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, Fa xprt->xp_fd is the transport's socket descriptor. This routine returns NULL if it fails. Since UNIX 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 Fa sendsize and Fa 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 Fa sendsize and Fa 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 Fa 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, Fa xprt->xp_fd is the transport's socket descriptor, and Fa 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.

Vt struct 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.
