rpc_svc_err(3NSL) Networking Services Library Functions rpc_svc_err(3NSL)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 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(3NSL) 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(3NSL)).
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, const rpcvers_t low_vers,
const rpcvers_t high_vers);
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 usu‐
ally 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) authentica‐
tion parameters. The routine calls svcerr_auth(xprt, AUTH_TOOWEAK).
