NAME
      rpcbind:   rpcbgetmaps, rpcbgetaddr, rpcbgettime, rpcbrmtcall,
      rpcbset, rpcbunset - library routines for RPC bind service

DESCRIPTION
      These routines allow client C programs to make procedure calls to the RPC
      binder service.  rpcbind [see rpcbind(1M)] maintains a list of mappings
      between programs and their universal addresses.

   Routines
      #include <rpc/rpc.h>

      struct rpcblist *
      rpcbgetmaps(const struct netconfig *netconf, const char *host);

            A user interface to the rpcbind service, which returns a list of
            the current RPC program-to-address mappings on the host named.  It
            uses the transport specified through netconf to contact the remote
            rpcbind service on host host.  This routine will return NULL, if
            the remote rpcbind could not be contacted.

      boolt
      rpcbgetaddr(const ulong prognum, const ulong versnum,
            const struct netconfig *netconf, struct netbuf *svcaddr,
            const char *host);

            A user interface to the rpcbind service, which finds the address of
            the service on host that is registered with program number prognum,
            version versnum, and speaks the transport protocol associated with
            netconf.  The address found is returned in svcaddr.  svcaddr should
            be preallocated.  This routine returns 1 if it succeeds.  A return
            value of 0 means that the mapping does not exist or that the RPC
            system failed to contact the remote rpcbind service.  In the latter
            case, the global variable rpccreateerr contains the RPC status.

      boolt
      rpcbgettime(const char *host, timet *timep);

            This routine returns the time on host in timep.  If host is NULL,
            rpcbgettime returns the time on its own machine.  This routine
            returns 1 if it succeeds, 0 if it fails.  rpcbgettime can be used
            to synchronize the time between the client and the remote server.
            This routine is particularly useful for secure RPC.

      enum clntstat
      rpcbrmtcall(const struct netconfig *netconf, const char *host,
            const ulong prognum, const ulong versnum, const ulong procnum,
            const xdrproct inproc, const caddrt in,
            const xdrproct outproc, const caddrt out,
            const struct timeval tout, struct netbuf  *svcaddr);

rpcbind(3N)                      UNIX System V                      rpcbind(3N)


            A user interface to the rpcbind service, which instructs rpcbind on
            host to make an RPC call on your behalf to a procedure on that
            host.  The parameter *svcaddr will be modified to the server's
            address if the procedure succeeds [see rpccall and clntcall in
            rpcclntcalls(3N) for the definitions of other parameters].  This
            procedure should normally be used for a ping and nothing else [see
            rpcbroadcast in rpcclntcalls(3N)].  This routine allows programs
            to do lookup and call, all in one step.

      boolt
      rpcbset(const ulong prognum, const ulong versnum,
            const struct netconfig *netconf, const struct netbuf *svcaddr);

            A user interface to the rpcbind service, which establishes a
            mapping between the triple [prognum, versnum, netconf->ncnetid]
            and svcaddr on the machine's rpcbind service.  The value of
            transport must correspond to a network token that is defined by the
            netconfig database.  This routine returns 1 if it succeeds, 0
            otherwise.  [See also svcreg in rpcsvccalls(3N)].

      boolt
      rpcbunset(const ulong prognum, const ulong versnum,
            const struct netconfig *netconf);

            A user interface to the rpcbind service, which destroys all mapping
            between the triple [prognum, versnum, netconf->ncnetid] and the
            address on the machine's rpcbind service.  If netconf is NULL,
            rpcbunset destroys all mapping between the triple [prognum,
            versnum, *] and the addresses on the machine's rpcbind service.
            This routine returns 1 if it succeeds, 0 otherwise.  [See also
            svcunreg in rpcsvccalls(3N)].
