+
+// This header is meant to be included in multiple passes, hence no traditional
+// header guard.
+//
+// In the first pass, IPC_MESSAGE_MACROS_ENUMS should be defined, which will
+// create enums for each of the messages defined with the IPC_MESSAGE_* macros.
+//
+// In the second pass, either IPC_MESSAGE_MACROS_DEBUGSTRINGS or
+// IPC_MESSAGE_MACROS_CLASSES should be defined (if both, DEBUGSTRINGS takes
+// precedence).  Only one .cc file should have DEBUGSTRINGS defined, as this
+// will create helper functions mapping message types to strings.  Having
+// CLASSES defined will create classes for each of the messages defined with
+// the IPC_MESSAGE_* macros.
+//
+// "Sync" messages are just synchronous calls, the Send() call doesn't return
+// until a reply comes back.  Input parameters are first (const TYPE&), and
+// To declare a sync message, use the IPC_SYNC_ macros.  The numbers at the
+// end show how many input/output parameters there are (i.e. 1_2 is 1 in, 2
+// out). The caller does a Send([route id, ], in1, &out1, &out2).
+// The receiver's handler function will be
+//     void OnSyncMessageName(const type1& in1, type2* out1, type3* out2)
+//
+//
+// A caller can also send a synchronous message, while the receiver can respond
+// at a later time.  This is transparent from the sender's size.  The receiver
+// needs to use a different handler that takes in a IPC::Message* as the output
+// type, stash the message, and when it has the data it can Send the message.
+//
+// Use the IPC_MESSAGE_HANDLER_DELAY_REPLY macro instead of IPC_MESSAGE_HANDLER
+//     IPC_MESSAGE_HANDLER_DELAY_REPLY(ViewHostMsg_SyncMessageName,
+//                                     OnSyncMessageName)
+//
+// The handler function will look like:
+//     void OnSyncMessageName(const type1& in1, IPC::Message* reply_msg);
+//
+// Receiver stashes the IPC::Message* pointer, and when it's ready, it does:
+//     ViewHostMsg_SyncMessageName::WriteReplyParams(reply_msg, out1, out2);
+//     Send(reply_msg);
