Routine Description:

    Called when a new adapter should be registered. It allocates space for
    the adapter, initializes the adapter's block, registers resources
    with the wrapper and initializes the physical adapter.

Arguments:

    Adapter - The adapter structure.

    ConfigurationHandle - Handle passed to CelanInitialize.

    ConfigError - Was there an error during configuration reading.

    ConfigErrorValue - Value to log if there is an error.

Return Value:

    Indicates the success or failure of the registration.
