RPC_SVC_ERR(3) FreeBSD Library Functions 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(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_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).
