See rpc(3NSL) for the definition of the SVCXPRT data structure.

#include <rpc/rpc.h>

void svcerr_auth(const SVCXPRT *xprt, const enum auth_stat why);

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

void svcerr_decode(const SVCXPRT *xprt);

Called by a service dispatch routine that cannot successfully decode the remote parameters (see svc_getargs() in rpc_svc_reg(3NSL)).

void svcerr_noproc(const SVCXPRT *xprt);

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

void svcerr_noprog(const SVCXPRT *xprt);

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

void svcerr_progvers(const SVCXPRT *xprt, const rpcvers_t low_vers, const rpcvers_t high_vers);

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

void svcerr_systemerr(const SVCXPRT *xprt);

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.

void svcerr_weakauth(const SVCXPRT *xprt);

Called by a service dispatch routine that refuses to perform a remote procedure call due to insufficient (but correct) authentication parameters. The routine calls svcerr_auth(xprt, AUTH_TOOWEAK).
