RPC_SVC_ERR(3)            NetBSD Programmer's Manual            RPC_SVC_ERR(3)


NAME

     rpc_svc_err, svcerr_auth, svcerr_decode, svcerr_noproc, svcerr_noprog,
     svcerr_progvers, svcerr_systemerr, svcerr_weakauth - library routines for
     server side remote procedure call errors


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <rpc/rpc.h>

     void
     svcerr_auth(const SVCXPRT1 *xprt, const enum auth_stat why);

     void
     svcerr_decode(const SVCXPRT *xprt);

     void
     svcerr_noproc(const SVCXPRT *xprt);

     void
     svcerr_noprog(const SVCXPRT *xprt);

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

     void
     svcerr_systemerr(const SVCXPRT *xprt);

     void
     svcerr_weakauth(const 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 decode the remote parameters (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.  low_vers is the lowest version number, and
            high_vers is the highest version number.  Service implementors
            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 parameters.  The routine calls svcerr_auth(xprt,
            AUTH_TOOWEAK).
