 // 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 tag,
+//                       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.
