Detailed Description

template<typename MTYPE>
struct L4::Ipc::Msg::Svr_val_ops< MTYPE >

Defines server-side handling of 'MTYPE' as RPC argument.

This provides the default implementation for trivially copyable data types. Other types override the marshalling operations by partially specializing Svr_val_ops.

The template is always instantiated with the Elem<ARG>::svr_type of the IPC method signature.

Template Parameters
MTYPEElem<T>::arg_type (where T is the type used in the RPC definition)
