       rpc - library routines for remote procedure calls

SYNOPSIS AND DESCRIPTION         top

       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.

       To take use of these routines, include the header file
       <rpc/rpc.h>.

       The prototypes below make use of the following types:

           typedef int bool_t;

           typedef bool_t (*xdrproc_t) (XDR *, void *, ...);

           typedef bool_t (*resultproc_t) (caddr_t resp,
                                           struct sockaddr_in *raddr);

       See the header files for the declarations of the AUTH, CLIENT,
       SVCXPRT, and XDR types.

       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(void);

              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 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(void);

              Calls authunix_create() with the appropriate parameters.

       int callrpc(char *host, unsigned long prognum,
                   unsigned long versnum, unsigned long procnum,
                   xdrproc_t inproc, char *in,
                   xdrproc_t outproc, char *out);

              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(unsigned long prognum,
                            unsigned long versnum, unsigned long procnum,
                            xdrproc_t inproc, char *in,
                            xdrproc_t outproc, char *out,
                            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(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(CLIENT *clnt, unsigned 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
              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(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, unsigned long prog,
                           unsigned long 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 hold only 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, int req, 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_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.

       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
              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(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);

              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.

       void clnt_perrno(enum clnt_stat stat);

              Print a message to standard error corresponding to the
              condition indicated by stat.  Used after callrpc().

       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.  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 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(3), or if a message format different than 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(unsigned long prognum, unsigned 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,
                       unsigned long prognum, unsigned long versnum,
                       int *sockp, unsigned int sendsz, unsigned 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 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(struct sockaddr_in *addr,
                       unsigned long prognum, unsigned long 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 hold only 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,
                   unsigned long prognum, unsigned 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 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().

              This allows the user to specify the maximum packet size
              for sending and receiving UDP-based RPC messages.

       void 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).

       struct pmaplist *pmap_getmaps(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.

       unsigned short pmap_getport(struct sockaddr_in *addr,
                           unsigned long prognum, unsigned long versnum,
                           unsigned int 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 failed to contact the remote portmap service.
              In the latter case, the global variable rpc_createerr
              contains the RPC status.

       enum clnt_stat pmap_rmtcall(struct sockaddr_in *addr,
                           unsigned long prognum, unsigned long versnum,
                           unsigned long procnum,
                           xdrproc_t inproc, char *in,
                           xdrproc_t outproc, char *out,
                           struct timeval tout, unsigned 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().

       bool_t pmap_set(unsigned long prognum, unsigned long versnum,
                       unsigned int protocol, unsigned 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().

       bool_t pmap_unset(unsigned long prognum, unsigned long 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.

       int registerrpc(unsigned long prognum, unsigned long versnum,
                       unsigned long procnum, char *(*procname)(char *),
                       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 parameter(s); procname 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 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.

       void 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 parameter to
              the select(2) system call.  This is of interest only if a
              service implementor does their own asynchronous event
              processing, instead of calling svc_run().  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.

       int svc_fds;

              Similar to svc_fdset, but limited to 32 file descriptors.
              This interface is obsoleted by svc_fdset.

       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.

       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 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 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 of interest only 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 file
              descriptors.  This interface is obsoleted by
              svc_getreqset().

       bool_t svc_register(SVCXPRT *xprt, unsigned long prognum,
                           unsigned long versnum,
                           void (*dispatch)(svc_req *, SVCXPRT *),
                           unsigned 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
              nonzero, 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(struct svc_req *request, SVCXPRT *xprt);

              The svc_register() routine returns one if it succeeds, and
              zero otherwise.

       void svc_run(void);

              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 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(unsigned long prognum, unsigned 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 parameters.  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);

              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 parameters.  The routine calls
              svcerr_auth(xprt, AUTH_TOOWEAK).

       SVCXPRT *svcfd_create(int fd, unsigned int sendsize,
                             unsigned int recvsize);

              Create a service on top of any open file descriptor.
              Typically, this file 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 *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, unsigned int send_buf_size,
                              unsigned 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_sock 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 *svcudp_bufcreate(int sock, unsigned int sendsize,
                                 unsigned int recosize);

              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.

              This allows the user to specify the maximum packet size
              for sending and receiving UDP-based RPC messages.

       SVCXPRT *svcudp_create(int sock);

              This call is equivalent to svcudp_bufcreate(sock,SZ,SZ)
              for some default size SZ.

       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 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.

       bool_t xdr_pmap(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.

       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 parameters 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.
