-// This header defines the CrossCall(..) family of templated functions
-// Their purpose is to simulate the syntax of regular call but to generate
-// and IPC from the client-side.
-//
-// The basic pattern is to
-//   1) use template argument deduction to compute the size of each
-//      parameter and the appropriate copy method
-//   2) pack the parameters in the appropriate ActualCallParams< > object
-//   3) call the IPC interface IPCProvider::DoCall( )
-//
-// The general interface of CrossCall is:
-//  ResultCode CrossCall(IPCProvider& ipc_provider,
-//                       uint32_t tag,
-//                       const Par1& p1, const Par2& p2,...pn
-//                       CrossCallReturn* answer)
-//
-//  where:
-//    ipc_provider: is a specific implementation of the ipc transport see
-//                  sharedmem_ipc_server.h for an example.
-//    tag : is the unique id for this IPC call. Is used to route the call to
-//          the appropriate service.
-//    p1, p2,.. pn : The input parameters of the IPC. Use only simple types
-//                   and wide strings (can add support for others).
-//    answer : If the IPC was successful. The server-side answer is here. The
-//             interpretation of the answer is private to client and server.
-//
-// The return value is ALL_OK if the IPC was delivered to the server, other
-// return codes indicate that the IPC transport failed to deliver it.
