DESCRIPTION

33     These routines are part of the RPC library which allows C language pro‐
34     grams to make procedure calls on other machines across the network.
35
36     These routines can be called by the server side dispatch function if
37     there is any error in the transaction with the client.
38

Routines

40     See rpc(3) for the definition of the SVCXPRT data structure.
41
42     svcerr_auth()
43            Called by a service dispatch routine that refuses to perform a
44            remote procedure call due to an authentication error.
45
46     svcerr_decode()
47            Called by a service dispatch routine that cannot successfully
48            decode the remote arguments (see svc_getargs() in rpc_svc_reg(3)).
49
50     svcerr_noproc()
51            Called by a service dispatch routine that does not implement the
52            procedure number that the caller requests.
53
54     svcerr_noprog()
55            Called when the desired program is not registered with the RPC
56            package.  Service implementors usually do not need this routine.
57
58     svcerr_progvers()
59            Called when the desired version of a program is not registered
60            with the RPC package.  The low_vers argument is the lowest version
61            number, and high_vers is the highest version number.  Service
62            implementors usually do not need this routine.
63
64     svcerr_systemerr()
65            Called by a service dispatch routine when it detects a system
66            error not covered by any particular protocol.  For example, if a
67            service can no longer allocate storage, it may call this routine.
68
69     svcerr_weakauth()
70            Called by a service dispatch routine that refuses to perform a
71            remote procedure call due to insufficient (but correct) authenti‐
72            cation arguments.  The routine calls svcerr_auth(xprt,
73            AUTH_TOOWEAK).
74
