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(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 suc

cessfully
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 cor

rect) authentication arguments. The routine calls

svcerr_auth(xprt,
AUTH_TOOWEAK).
