rpc_svc_err(3N)

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

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
     svcerr_auth(const SVCXPRT *xprt, const enum auth_stat why);

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

     void
     svcerr_decode(const SVCXPRT *xprt);

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

     void
     svcerr_noproc(const SVCXPRT *xprt);

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

     void
     svcerr_noprog(const SVCXPRT *xprt);

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

     void
     svcerr_progvers(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.

     void
     svcerr_systemerr(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
     svcerr_weakauth(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 svcerr_auth(xprt,
          AUTH_TOOWEAK).
