why);

void svcerr_systemerr(const SVCXPRT *
xprt);
void svcerr_weakauth(const 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.
The HP-UX implementation of RPC only supports the X/Open Transport Interface (XTI). Applications that
are written using the Transport Layer Interface (TLI) and wish to use RPC, must convert their application
to XTI.
Routines
See rpc(3N) for the definition of the SVCXPRT data structure.
void svcerr_auth()
Called by a service dispatch routine that refuses to perform a remote procedure call due to an authen-
tication error.
void svcerr_decode()
Called by a service dispatch routine that cannot successfully decode the remote parameters (see
svc_getargs() in rpc_svc_reg(3N)).
void svcerr_noproc()
Called by a service dispatch routine that does not implement the procedure number that the caller
requests.
void svcerr_noprog()
Called when the desired program is not registered with the RPC package. Service implementors usu-
ally do not need this routine.
void svcerr_progvers()
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 usually
do not need this routine.
void svcerr_systemerr()
Called by a service dispatch routine when it detects a system error not covered by any particular pro-
tocol. For example, if a service can no longer allocate storage, it may call this routine.
void svcerr_weakauth()
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)
.
