Initialize the memory region variables from the global variables when creating
the LUC Endpoint object. Changes to the global variables are propagated to new
endpoint objects, not objects that already exist. An endpoint's memory configuration
variables may be changed by using the
LucEndpoint::setConfigValue()
method until the endpoint is started. Once the endpoint starts, the size of the
nearby memory regions and the maximum transfer sizes are locked in and
may not be modified until you stop the endpoint. Attempts to change these
configuration variables by using LucEndpoint::setConfigValue() fail
with LUC_ERR_INVALID_STATE. If you try to change the global configuration
variables, the changes do not propagate to started endpoints. Attempts to set invalid
memory sizes or maximum request sizes fail with LUC_ERR_BAD_PARAMETER.
