Returns a list of all errors for this connection object. This function also clears the error list. The errors are stored in LIFO order, so the last error which happend is stored as the first element in the list. Advancing the list means to get back in time and retrieve earlier errors.
The farther away from the client the error happens, the later it is in the queue. If an error happens on the client and then in the CORBA layer and then on the server, you will get the server error first.
