Detailed Description

template<typename Derived, typename Base1, typename Base2, long PROTO = PROTO_ANY, typename S_DEMAND = Type_info::Demand_t<>>
class L4::Kobject_2t< Derived, Base1, Base2, PROTO, S_DEMAND >

Helper class to create an L4Re interface class that is derived from two base classes (see L4::Kobject_t).

Template Parameters
Derivedis the name of the new interface.
Base1is the name of the interface's first base class.
Base2is the name of the interface's second base class.
PROTOmay be set to the statically assigned protocol number used to communicate with this interface.
S_DEMANDtype defining the demand of server-side resources for this interface, usually a L4::Type_info::Demand_t. This value must describe the server-side resources needed by the interface itself, the resource demand of the base interfaces (Base1 and Base2) are automatically included.

The typical usage pattern is shown in the following code snippet. The semantics of this example is an interface My_iface that is derived from L4::Icu and L4Re::Dataspace.

class My_iface : public L4::Kobject_2t<My_iface, L4::Icu, L4Re::Dataspace>
{
...
};
