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 Vt SVCXPRT data structure.

Fn svcerr_auth

Called by a service dispatch routine that refuses to perform a remote procedure call due to an authentication error.

Fn svcerr_decode

Called by a service dispatch routine that cannot successfully decode the remote arguments (see Fn svc_getargs in rpc_svc_reg3).

Fn svcerr_noproc

Called by a service dispatch routine that does not implement the procedure number that the caller requests.

Fn svcerr_noprog

Called when the desired program is not registered with the RPC package. Service implementors usually do not need this routine.

Fn svcerr_progvers

Called when the desired version of a program is not registered with the RPC package. The Fa low_vers argument is the lowest version number, and Fa high_vers is the highest version number. Service implementors usually do not need this routine.

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.

Fn 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 Fn svcerr_auth xprt AUTH_TOOWEAK .

AVAILABILITY

These functions are part of libtirpc.
