void TAO_Adapter_Registry::check_close

(

int

wait_for_completion

)

Verify if the close() call can be invoked in the current context for *all* adapters. Raise the right exception if not.

    }
}

void TAO_Adapter_Registry::close

(

int

wait_for_completion

)

Close each of of the Adapters and then cleanup the Registry. It is possible that an Adapter will reject a close() call if it is invoked in an innapropriate context (think shutting down the POA while performing an upcall).
