.Sh DESCRIPTION
|
|
These routines are part of the RPC
|
|
library which allows C language programs to make procedure
|
|
calls on other machines across the network.
|
|
.Pp
|
|
These routines can be called by the server side
|
|
dispatch function if there is any error in the
|
|
transaction with the client.
|
|
.Sh Routines
|
|
See
|
|
.Xr rpc 3
|
|
for the definition of the
|
|
.Vt SVCXPRT
|
|
data structure.
|
|
.Bl -tag -width XXXXX
|
|
.It Fn svcerr_auth
|
|
Called by a service dispatch routine that refuses to perform
|
|
a remote procedure call due to an authentication error.
|
|
.It Fn svcerr_decode
|
|
Called by a service dispatch routine that cannot successfully
|
|
decode the remote parameters
|
|
(see
|
|
.Fn svc_getargs
|
|
in
|
|
.Xr rpc_svc_reg 3 ) .
|
|
.It Fn svcerr_noproc
|
|
Called by a service dispatch routine that does not implement
|
|
the procedure number that the caller requests.
|
|
.It Fn svcerr_noprog
|
|
Called when the desired program is not registered with the
|
|
RPC package.
|
|
Service implementors usually do not need this routine.
|
|
.It Fn svcerr_progvers
|
|
Called when the desired version of a program is not registered with the
|
|
RPC package.
|
|
.Fa low_vers
|
|
is the lowest version number,
|
|
and
|
|
.Fa high_vers
|
|
is the highest version number.
|
|
Service implementors usually do not need this routine.
|
|
.It Fn 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.
|
|
.It Fn 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
|
|
.Fn svcerr_auth "xprt" "AUTH_TOOWEAK" .
