typedef L4::Type_info::Demand | Demand |
Data type expressing server-side demand for receive buffers. | |
Empty implementation of Server_iface.
This implementation of Server_iface provides no buffer or timeout management at all it just returns errors for all calls that express other than empty demands. However, this may be useful for very simple servers that serve simple server objects only.

inlineoverridevirtual |
Tells the server to allocate buffers for the given demand.
demand | The total server-side demand of receive buffers needed for a given interface, see Demand. |
This function is not called by user applications directly. Usually the server implementation or the registry implementation calls this function whenever a new object is registered at the server.
Implements L4::Ipc_svr::Server_iface.
