NAME
       rpc - library routines for remote procedure calls

SYNOPSIS AND DESCRIPTION
       These  routines allow C programs to make procedure calls on other machines across the net-
       work.  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 ser-
       vice, 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  infor-
	      mation.  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 deal-
	      location of private data structures, including clnt itself.  Use of clnt	is  unde-
	      fined  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  time-
	      outs 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 out-
	      proc 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_spcreaterror(), 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  ver-
	      snum.   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  inter-
	      ference.	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 parame-
	      ters 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 Inter-
	      net  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 rou-
	      tine 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);  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  other-
	      wise.

	      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 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.

       int svc_fds;

	      Similar to svc_fdset, but limited to 32 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 ser-
	      vice 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 rou-
	      tine 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  asso-
	      ciated 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 descriptors.  This interface is obso-
	      leted 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 pro-
	      tocol 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  proce-
	      dure  call.   The parameter xprt is the request's associated transport handle; out-
	      proc 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 parame-
	      ters.  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  pack-
	      age.  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 descriptor.  Typically, this descriptor is a
	      connected socket for a stream protocol such as TCP.  sendsize and recvsize indicate
	      sizes  for the send and receive buffers.	If they are zero, a reasonable default is
	      chosen.

       SVCXPRT *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 corre-
	      sponding 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  comple-
	      tion,  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 comple-
	      tion, 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  use-
	      ful  for	users who wish to generate RPC-style messages without using the RPC pack-
	      age.

       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.
