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

SYNOPSIS

     #include <rpc/rpc.h>

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

     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 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(3) for the definition of the SVCXPRT data structure.

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

     svcerr_decode()
            Called by a service dispatch routine that cannot successfully decode 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 implementors usually do not need this routine.

     svcerr_systemerr()
            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.

     svcerr_weakauth()
            Called by a service dispatch routine that refuses to perform a remote procedure call
            due to insufficient (but correct) authentication arguments.  The routine calls
            svcerr_auth(xprt, AUTH_TOOWEAK).

AVAILABILITY

     These functions are part of libtirpc.
