     void
     svcerr_decode(SVCXPRT *xprt);

     void
     svcerr_noproc(SVCXPRT *xprt);

     void
     svcerr_noprog(SVCXPRT *xprt);

     void
     svcerr_progvers(SVCXPRT *xprt, rpcvers_t low_vers, rpcvers_t high_vers);

     void
     svcerr_systemerr(SVCXPRT *xprt);

     void
     svcerr_weakauth(SVCXPRT *xprt);

DESCRIPTION
     These routines are part of the RPC library which allows C language pro-
     grams 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(3) for the definition of the SVCXPRT data structure.

     svcerr_auth()
            Called by a service dispatch routine that refuses to perform a re-
            mote procedure call due to an authentication error.

     svcerr_decode()
            Called by a service dispatch routine that cannot successfully de-
            code the remote arguments (see svc_getargs() in rpc_svc_reg(3)).

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

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

     svcerr_progvers()
            Called when the desired version of a program is not registered
            with the RPC package.  The low_vers argument is the lowest version
            number, and high_vers is the highest version number.  Service im-
            plementors usually do not need this routine.

     svcerr_systemerr()
            Called by a service dispatch routine when it detects a system er-
            ror not covered by any particular protocol.  For example, if a
            service can no longer allocate storage, it may call this routine.

     svcerr_weakauth()
            Called by a service dispatch routine that refuses to perform a re-
            mote procedure call due to insufficient (but correct) authentica-
            tion arguments.  The routine calls svcerr_auth(xprt,
            AUTH_TOOWEAK).

AVAILABILITY
     These functions are part of libtirpc.
