Detailed Description

template<typename IFACE, typename BASE = L4::Server_object>
struct L4::Server_object_t< IFACE, BASE >

Base class (template) for server implementing server objects.

Template Parameters

IFACE	The IPC interface class that defines the interface that shall be implemented.
BASE	The server object base class (usually L4::Server_object).

Examples

examples/libs/l4re/c++/shared_ds/ds_srv.cc, and examples/libs/l4re/streammap/server.cc.

Member Function Documentation

dispatch_meta_request()

template<typename IFACE, typename BASE = L4::Server_object>

int L4::Server_object_t< IFACE, BASE >::dispatch_meta_request ( L4::Ipc::Iostream & ios )

inline

Implementation of the meta protocol based on IFACE.

Parameters

ios	The IO stream used for receiving the message.

This function can be used to handle incoming L4_PROTO_META protocol requests. The implementation uses the L4::Type_info of IFACE to handle the requests. Call this function in the implementation of Server_object::dispatch() when the received message tag has protocol L4_PROTO_META (L4::Meta::Protocol).

Definition at line 99 of file ipc_server.

get_buffer_demand()

template<typename IFACE, typename BASE = L4::Server_object>

BASE::Demand L4::Server_object_t< IFACE, BASE >::get_buffer_demand ( ) const

inlineoverridevirtual

Returns

the server-side buffer demand based in IFACE.

Implements L4::Epiface.

Definition at line 86 of file ipc_server.

proto_dispatch()

template<typename IFACE, typename BASE = L4::Server_object>

template<typename THIS>

int L4::Server_object_t< IFACE, BASE >::proto_dispatch ( THIS * self, l4_umword_t rights, L4::Ipc::Iostream & ios )

inlinestatic

Implementation of protocol-based dispatch for this server object.

Parameters

self	The this pointer for the object (inherits from Server_object_t).
rights	The rights from the received IPC (forwarded to p_dispatch()).
ios	The message stream for the incoming and the reply message.

Server objects may call this function from their dispatch() function. This function reads the protocol ID from the message tag and uses the p_dispatch code to dispatch to overloaded p_dispatch functions of self.
