c++ 实现fdbus

FDBus是一个基于C++的轻量级进程间通信框架，其实现原理主要是通过共享内存和消息队列来实现进程间通信。下面是一个简单的FDBus实现示例：

1. 首先需要定义消息结构体，例如定义一个名为MyMessage的消息结构体：

struct MyMessage {
    int id;
    std::string data;
};

2. 创建FDBus对象，并注册消息处理函数：

fdbus::CFdbContext fdb_context;
fdbus::CBaseWorker *worker = new fdbus::CBaseWorker(&fdb_context);
fdbus::CFdbSessionContainer *session_container = new fdbus::CFdbSessionContainer();
fdbus::CMethodLoopThread *thread = new fdbus::CMethodLoopThread(&fdb_context);

class MyService : public fdbus::CBaseServer {
public:
    MyService() : fdbus::CBaseServer("MyService") {}
    void onMessage(int sn, const std::string &type, const void *buffer, int size) {
        MyMessage *msg = (MyMessage*)buffer;
        std::cout << "Received message: " << msg->id << " " << msg->data << std::endl;
    }
};

MyService my_service;
my_service.bind(&fdb_context, "MyService");

session_container->createSession("MySession", "MyService", true);
fdb_context.start();

3. 发送消息：

MyMessage msg;
msg.id = 123;
msg.data = "Hello, world!";
session_container->sendMessage("MySession", "MyService", &msg, sizeof(msg), 0);

以上是一个简单的FDBus实现示例，具体实现还需要根据需求进行调整和完善。
