NAME
rpc_mgmt_inq_if_ids - Returns a vector of interface identifiers of
interfaces a server offers
Used by client, server, or management applications.
SYNOPSIS
#include <dce/rpc.h>
void rpc_mgmt_inq_if_ids( rpc_binding_handle_t binding,
rpc_if_id_vector_t **if_id_vector,
unsigned32 *status );
PARAMETERS
Input
binding
Specifies a binding handle. To receive interface identifiers
from a remote application, specify a server binding handle for
that application. To receive interface information about your
own (local) application, specify NULL.
If the binding handle you supply refers to partially bound binding
information and the binding information contains a nil object
UUID, this routine returns the rpc_s_binding_incomplete status
code. In this case, the DCE Host Daemon (dced) does not know which
serveR instance to select from the local endpoint map because the
RPC management interface is automatically registered (by the RPC
runtime) for all RPC servers. To avoid this situation, you can
obtain a fully bound server binding handle by calling the
rpc_ep_resolve_binding() routine.
Output
if_id_vector
Returns the address of an interface identifier vector.
status
Returns the status code from this routine, which indicates
whether the routine completed successfully or, if not, why
not. The possible status codes and their meanings are as follows:
rpc_s_ok Success.
rpc_s_binding_incomplete
Binding incomplete (no object ID and no endpoint).
rpc_s_comm_failure
Communications failure.
rpc_s_invalid_arg
Invalid argument.
rpc_s_invalid_binding
Invalid binding handle.
rpc_s_mgmt_op_disallowed
Management operation disallowed.
rpc_s_no_interfaces
No interfaces registered.
rpc_s_wrong_kind_of_binding
Wrong kind of binding for operation.
In addition to the values above, status can return the value of
parameter status from the application-defined authorization function
(rpc_mgmt_authorization_fn_t). The prototype for such a function is
defined in the authorization_fn parameter listed in the reference page
for the rpc_mgmt_set_authorization_fn routine.
DESCRIPTION
An application calls the rpc_mgmt_inq_if_ids() routine to obtain a
vector of interface identifiers listing the interfaces registered by
a server with the RPC runtime.
If a server has not registered any interfaces with the runtime, this
routine returns a rpc_s_no_interfaces status code and an if_id_vector
parameter value of NULL.
The application calls the rpc_if_id_vector_free() routine to release
the memory used by the vector.
By default, the RPC runtime allows all clients to remotely call
this routine. To restrict remote calls of this routine, a server
application supplies an authorization function using the
rpc_mgmt_set_authorization_fn() routine.
RETURN VALUES
No value is returned.
