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 parameters (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. low_vers 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 parameters. The routine calls
svcerr_auth(xprt,
AUTH_TOOWEAK).
