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_progvers
()
- Called when the desired version of a program is not registered with the
RPC package. The low_vers argument 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 arguments.
The routine calls
svcerr_auth
(xprt,
AUTH_TOOWEAK).
AVAILABILITY¶
These functions are part of libtirpc.
