// Use of this source code is governed by a BSD-style license that can be
// found in the LICENSE file.

// 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);
