rpc_register_mgr(3ncs)

Name

rpc_register_mgr − register a manager (server only)

Syntax

#include <idl/c/rpc.h>

void rpc_$register_mgr(type, ifspec, sepv, mepv, status)

uuid_$t *type;
rpc_$if_spec_t *ifspec;
rpc_$generic_epv_t sepv;
rpc_$mgr_epv_t mepv;
status_$t *status;

Arguments

type The UUID of the type being registered.

ifspec The interface being registered.

sepv The generic EPV, a vector of pointers to server stub procedures.

mepv The manager EPV, a vector of pointers to manager procedures.

status The completion status. If the completion status returned in status.all is equal to status_$ok , then the routine that supplied it was successful.

Description

The rpc_$register_mgr routine registers the set of manager procedures that implement a specified interface for a specified type.

Servers can invoke this routine several times with the same interface (ifspec) and generic EPV (sepv) but with a different object type (type) and manager EPV (mepv) on each invocation. This technique allows a server to export several implementations of the same interface.

Servers that export several versions of the same interface (but not different implementations for different types) must also use rpc_$register_mgr, not rpc_$register. Such servers should supply uuid_$nil as the type to rpc_$register_mgr.

If a server uses rpc_$register_mgr to register a manager for a specific interface and a specific type that is not nil, the server must use rpc_$register_object to register an object.

Diagnostics

This section lists status codes for errors returned by this rpc_$ routine in status.all.

rpc_$op_rng_error
The requested operation does not correspond to a valid operation in the requested interface.

rpc_$unk_if The requested interface is not known. It is not registered in the server, the version number of the registered interface is different from the version number specified in the request, or the UUID in the request does not match the UUID of the registered interface.

rpc_$too_many_ifs
The maximum number of interfaces is already registered with the RPC runtime library; the server must unregister some interface before it registers an additional interface.

rpc_$not_in_call An internal error.

rpc_$you_crashed This error can occur if a server has crashed and restarted. A client RPC runtime library sends the error to the server if the client makes a remote procedure call before the server crashes, then receives a response after the server restarts.

rpc_$proto_error An internal protocol error.

rpc_$illegal_register
You are trying to register an interface that is already registered and you are using an EPV different from the one used when the interface was first registered. An interface can be multiply registered, but you must use the same EPV in each rpc_$register routine.
