DESCRIPTION

36     These routines are part of the RPC library which allows C language pro‐
37     grams to make procedure calls on other machines across the network.
38
39     These routines can be called by the server side dispatch function if
40     there is any error in the transaction with the client.
41

Routines

43     See rpc(3) for the definition of the SVCXPRT data structure.
44
45     svcerr_auth()
46            Called by a service dispatch routine that refuses to perform a
47            remote procedure call due to an authentication error.
48
49     svcerr_decode()
50            Called by a service dispatch routine that cannot successfully
51            decode the remote arguments (see svc_getargs() in rpc_svc_reg(3)).
52
53     svcerr_noproc()
54            Called by a service dispatch routine that does not implement the
55            procedure number that the caller requests.
56
57     svcerr_noprog()
58            Called when the desired program is not registered with the RPC
59            package.  Service implementors usually do not need this routine.
60
61     svcerr_progvers()
62            Called when the desired version of a program is not registered
63            with the RPC package.  The low_vers argument is the lowest version
64            number, and high_vers is the highest version number.  Service
65            implementors usually do not need this routine.
66
67     svcerr_systemerr()
68            Called by a service dispatch routine when it detects a system
69            error not covered by any particular protocol.  For example, if a
70            service can no longer allocate storage, it may call this routine.
71
72     svcerr_weakauth()
73            Called by a service dispatch routine that refuses to perform a
74            remote procedure call due to insufficient (but correct) authenti‐
75            cation arguments.  The routine calls svcerr_auth(xprt,
76            AUTH_TOOWEAK).
