NAME
     rpc_svc_reg:   svc_freeargs, svc_getargs, svc_getreqset,
     svc_getrpccaller, svc_run, svc_sendreply - library routines
     for RPC servers

DESCRIPTION
     These routines are part of the RPC library  which  allows  C
     language  programs to make procedure calls on other machines
     across the network.  These routines are associated with  the
     server  side  of the RPC mechanism.  Some of them are called
     by the server side dispatch function, while others [such  as
     svc_run] are called when the server is initiated.

  Routines
     #include <rpc/rpc.h>

     int
     svc_freeargs(const SVCXPRT *xprt, const xdrproc_t inproc, char *in);

          A function macro that frees any data allocated  by  the
          RPC/XDR  system when it decoded the arguments to a ser-
          vice procedure using svc_getargs.  This routine returns
          1  if the results were successfully freed, and 0 other-
          wise.
          int
          svc_getargs(const SVCXPRT *xprt, const xdrproc_t inproc, caddr_t *in);

          A function macro that decodes the arguments of  an  RPC
          request  associated with the RPC service transport han-
          dle 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  1
          if decoding succeeds, and 0 otherwise.

          void
          svc_getreqset(fd_set *rdfds);

          This routine is only of interest if a service implemen-
          tor  does not call svc_run, but instead implements cus-
          tom asynchronous event processing.  It is  called  when
          poll  has determined that an RPC request has arrived on
          some RPC file descriptors; rdfds is the resultant  read
          file descriptor bit mask.  The routine returns when all
          file descriptors associated with  the  value  of  rdfds
          have been serviced
          struct netbuf *
          svc_getrpccaller(const 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_run(void);

          This routine never returns.  It waits for RPC  requests
          to  arrive, and calls the appropriate service procedure
          using svc_getreqset when one arrives.   This  procedure
          is usually waiting for a poll library call to return.

          int
          svc_sendreply(const SVCXPRT *xprt, const xdrproc_t outproc,
               const caddr_t *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 1 if it succeeds, 0 otherwise.
