| // Defining IPC Messages |
| // |
| // Your IPC messages will be defined by macros inside of an XXX_messages.h |
| // header file. Most of the time, the system can automatically generate all |
| // of messaging mechanism from these definitions, but sometimes some manual |
| // coding is required. In these cases, you will also have an XXX_messages.cc |
| // implementation file as well. |
| // |
| // The senders of your messages will include your XXX_messages.h file to |
| // get the full set of definitions they need to send your messages. |
| // |
| // Each XXX_messages.h file must be registered with the IPC system. This |
| // requires adding two things: |
| // - An XXXMsgStart value to the IPCMessageStart enum in ipc_message_start.h |
| // - An inclusion of XXX_messages.h file in a message generator .h file |
| // |
| // The XXXMsgStart value is an enumeration that ensures uniqueness for |
| // each different message file. Later, you will use this inside your |
| // XXX_messages.h file before invoking message declaration macros: |
| // #define IPC_MESSAGE_START XXXMsgStart |
| // ( ... your macro invocations go here ... ) |
| // |
| // Message Generator Files |
| // |
| // A message generator .h header file pulls in all other message-declaring |
| // headers for a given component. It is included by a message generator |
| // .cc file, which is where all the generated code will wind up. Typically, |
| // you will use an existing generator (e.g. common_message_generator.cc |
| // in /chrome/common), but there are circumstances where you may add a |
| // new one. |
| // |
| // In the rare circumstances where you can't re-use an existing file, |
| // your YYY_message_generator.cc file for a component YYY would contain |
| // the following code: |
| // // Get basic type definitions. |
| // #define IPC_MESSAGE_IMPL |
| // #include "path/to/YYY_message_generator.h" |
| // // Generate constructors. |
| // #include "ipc/struct_constructor_macros.h" |
| // #include "path/to/YYY_message_generator.h" |
| // // Generate param traits write methods. |
| // #include "ipc/param_traits_write_macros.h" |
| // namespace IPC { |
| // #include "path/to/YYY_message_generator.h" |
| // } // namespace IPC |
| // // Generate param traits read methods. |
| // #include "ipc/param_traits_read_macros.h" |
| // namespace IPC { |
| // #include "path/to/YYY_message_generator.h" |
| // } // namespace IPC |
| // // Generate param traits log methods. |
| // #include "ipc/param_traits_log_macros.h" |
| // namespace IPC { |
| // #include "path/to/YYY_message_generator.h" |
| // } // namespace IPC |
| // |
| // In cases where manual generation is required, in your XXX_messages.cc |
| // file, put the following after all the includes for param types: |
| // #define IPC_MESSAGE_IMPL |
| // #include "XXX_messages.h" |
| // (... implementation of traits not auto-generated ...) |
| // |
| // Multiple Inclusion |
| // |
| // The XXX_messages.h file will be multiply-included by the |
| // YYY_message_generator.cc file, so your XXX_messages file can't be |
| // guarded in the usual manner. Ideally, there will be no need for any |
| // inclusion guard, since the XXX_messages.h file should consist solely |
| // of inclusions of other headers (which are self-guarding) and IPC |
| // macros (which are multiply evaluating). |
| // |
| // Note that #pragma once cannot be used here; doing so would mark the whole |
| // file as being singly-included. Since your XXX_messages.h file is only |
| // partially-guarded, care must be taken to ensure that it is only included |
| // by other .cc files (and the YYY_message_generator.h file). Including an |
| // XXX_messages.h file in some other .h file may result in duplicate |
| // declarations and a compilation failure. |
| // |
| // Type Declarations |
| // |
| // It is generally a bad idea to have type definitions in a XXX_messages.h |
| // file; most likely the typedef will then be used in the message, as opposed |
| // to the struct itself. Later, an IPC message dispatcher will need to call |
| // a function taking that type, and that function is declared in some other |
| // header. Thus, in order to get the type definition, the other header |
| // would have to include the XXX_messages.h file, violating the rule above |
| // about not including XXX_messages.h file in other .h files. |
| // |
| // One approach here is to move these type definitions to another (guarded) |
| // .h file and include this second .h in your XXX_messages.h file. This |
| // is still less than ideal, because the dispatched function would have to |
| // redeclare the typedef or include this second header. This may be |
| // reasonable in a few cases. |
| // |
| // Failing all of the above, then you will want to bracket the smallest |
| // possible section of your XXX_messages.h file containing these types |
| // with an include guard macro. Be aware that providing an incomplete |
| // class type declaration to avoid pulling in a long chain of headers is |
| // acceptable when your XXX_messages.h header is being included by the |
| // message sending caller's code, but not when the YYY_message_generator.c |
| // is building the messages. In addition, due to the multiple inclusion |
| // restriction, these type ought to be guarded. Follow a convention like: |
| // #ifndef SOME_GUARD_MACRO |
| // #define SOME_GUARD_MACRO |
| // class some_class; // One incomplete class declaration |
| // class_some_other_class; // Another incomplete class declaration |
| // #endif // SOME_GUARD_MACRO |
| // #ifdef IPC_MESSAGE_IMPL |
| // #include "path/to/some_class.h" // Full class declaration |
| // #include "path/to/some_other_class.h" // Full class declaration |
| // #endif // IPC_MESSAGE_IMPL |
| // (.. IPC macros using some_class and some_other_class ...) |
| // |
| // Macro Invocations |
| // |
| // You will use IPC message macro invocations for three things: |
| // - New struct definitions for IPC |
| // - Registering existing struct and enum definitions with IPC |
| // - Defining the messages themselves |
| // |
| // New structs are defined with IPC_STRUCT_BEGIN(), IPC_STRUCT_MEMBER(), |
| // IPC_STRUCT_END() family of macros. These cause the XXX_messages.h |
| // to proclaim equivalent struct declarations for use by callers, as well |
| // as later registering the type with the message generation. Note that |
| // IPC_STRUCT_MEMBER() is only permitted inside matching calls to |
| // IPC_STRUCT_BEGIN() / IPC_STRUCT_END(). There is also an |
| // IPC_STRUCT_BEGIN_WITH_PARENT(), which behaves like IPC_STRUCT_BEGIN(), |
| // but also accommodates structs that inherit from other structs. |
| // |
| // Externally-defined structs are registered with IPC_STRUCT_TRAITS_BEGIN(), |
| // IPC_STRUCT_TRAITS_MEMBER(), and IPC_STRUCT_TRAITS_END() macros. These |
| // cause registration of the types with message generation only. |
| // There's also IPC_STRUCT_TRAITS_PARENT, which is used to register a parent |
| // class (whose own traits are already defined). Note that |
| // IPC_STRUCT_TRAITS_MEMBER() and IPC_STRUCT_TRAITS_PARENT are only permitted |
| // inside matching calls to IPC_STRUCT_TRAITS_BEGIN() / |
| // IPC_STRUCT_TRAITS_END(). |
| // |
| // Enum types are registered with a single IPC_ENUM_TRAITS_VALIDATE() macro. |
| // There is no need to enumerate each value to the IPC mechanism. Instead, |
| // pass an expression in terms of the parameter |value| to provide |
| // range-checking. For convenience, the IPC_ENUM_TRAITS() is provided which |
| // performs no checking, passing everything including out-of-range values. |
| // Its use is discouraged. The IPC_ENUM_TRAITS_MAX_VALUE() macro can be used |
| // for the typical case where the enum must be in the range 0..maxvalue |
| // inclusive. The IPC_ENUM_TRAITS_MIN_MAX_VALUE() macro can be used for the |
| // less typical case where the enum must be in the range minvalue..maxvalue |
| // inclusive. |
| // |
| // Do not place semicolons following these IPC_ macro invocations. There |
| // is no reason to expect that their expansion corresponds one-to-one with |
| // C++ statements. |
| // |
| // Once the types have been declared / registered, message definitions follow. |
| // "Sync" messages are just synchronous calls, the Send() call doesn't return |
| // until a reply comes back. 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). Input parameters are first, followed by |
| // output parameters. The caller uses 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 side. 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) |
| // Unlike IPC_MESSAGE_HANDLER which works with IPC_BEGIN_MESSAGE_MAP as well as |
| // IPC_BEGIN_MESSAGE_MAP_WITH_PARAM, one needs to use |
| // IPC_MESSAGE_HANDLER_WITH_PARAM_DELAY_REPLY to properly handle the param. |
| // |
| // 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); |
| |
| // Files that want to export their ipc messages should do |
| // #undef IPC_MESSAGE_EXPORT |
| // #define IPC_MESSAGE_EXPORT VISIBILITY_MACRO |
| // after including this header, but before using any of the macros below. |
| // (This needs to be before the include guard.) |
