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 service procedure using
          svc_getargs.  This routine returns 1 if the results were
          successfully freed, and 0 otherwise.

     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 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 1 if decoding succeeds, and 0 otherwise.

     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 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.
