rpc_register(3ncs) rpc_register(3ncs)
Name
rpc_register - register an interface (server only)
Syntax
#include <idl/c/rpc.h>
void rpc_$register(ifspec, epv, status)
rpc_$if_spec_t *ifspec;
rpc_$epv_t epv;
status_$t *status;
Arguments
ifspec The interface being registered.
epv The entry point vector (EPV) for the operations in the interface. The EPV is always defined in the server stub that is
generated by the NIDL compiler from an interface definition.
status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it
was successful.
Description
The routine registers an interface with the RPC runtime library. After an interface is registered, the RPC runtime library will pass
requests for that interface to the server.
You can call several times with the same interface (for example, from various subroutines of the same server), but each call must specify
the same EPV. Each registration increments a reference count for the registered interface; an equal number of routines are then required
to unregister the interface.
Examples
The following statement registers the bank interface with the bank server host's RPC runtime library:
rpc_$register (&bank_$if_spec, bank_$server_epv, &status);
Diagnostics
This section lists status codes for errors returned by this routine in
rpc_$op_rng_error The requested operation does not correspond to a valid operation in the requested interface.
rpc_$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 routine.
rpc_$bad_pkt The server or client has received an ill-formed packet.
