 // This header is part of CrossCall: the sandbox inter-process communication.
 // This header defines the basic types used both in the client IPC and in the
 // server IPC code. CrossCallParams and ActualCallParams model the input
 // parameters of an IPC call and CrossCallReturn models the output params and
 // the return value.
 //
 // An IPC call is defined by its 'tag' which is a (uint32) unique identifier
 // that is used to route the IPC call to the proper server. Every tag implies
 // a complete call signature including the order and type of each parameter.
