rpc_svc_err(3N)                                             rpc_svc_err(3N)


   NAME
         rpcsvcerr:   svcerrauth, svcerrdecode, svcerrnoproc,
         svcerrnoprog, svcerrprogvers, svcerrsystemerr, svcerrweakauth -
         library routines for server side remote procedure call errors

   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 can be called by the server side dispatch function if
         there is any error in the transaction with the client.

      Routines
         See rpc(3N) for the definition of the SVCXPRT data structure.

         #include <rpc/rpc.h>

         void
         svcerrauth(const SVCXPRT *xprt, const enum authstat why);

               Called by a service dispatch routine that refuses to perform a
               remote procedure call due to an authentication error.

         void
         svcerrdecode(const SVCXPRT *xprt);

               Called by a service dispatch routine that cannot successfully
               decode the remote parameters [see svcgetargs in
               rpcsvcreg(3N)].

         void
         svcerrnoproc(const SVCXPRT *xprt);

               Called by a service dispatch routine that does not implement
               the procedure number that the caller requests.

         void
         svcerrnoprog(const SVCXPRT *xprt);

               Called when the desired program is not registered with the RPC
               package.  Service implementors usually do not need this
               routine.

         void
         svcerrprogvers(const 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.

   rpc_svc_err(3N)                                             rpc_svc_err(3N)


         void
         svcerrsystemerr(const 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
         svcerrweakauth(const SVCXPRT *xprt);

               Called by a service dispatch routine that refuses to perform a
               remote procedure call due to insufficient (but correct)
               authentication parameters.  The routine calls svcerrauth(xprt,
               AUTHTOOWEAK).
