在github上找了个轮子cpp-ipc，发现读不懂了，c++就是够够的。
主要是这种调用方法：
static bool send(ipc::handle_t h, void const * data, std::size_t size) {
    return send([](auto info, auto que, auto msg_id) {

上下文：
static bool send(ipc::handle_t h, void const * data, std::size_t size) {
    return send([](auto info, auto que, auto msg_id) {
        return [info, que, msg_id](std::int32_t remain, void const * data, std::size_t size) {
            if (!wait_for(info->wt_waiter_, [&] {
                    return !que->push(info->cc_id_, msg_id, remain, data, size);
                }, default_timeout)) {
                ipc::log("force_push: msg_id = %zd, remain = %d, size = %zd\n", msg_id, remain, size);
                if (!que->force_push([](void* p) {
                    auto tmp_msg = static_cast<typename queue_t::value_t*>(p);
                    if (tmp_msg->storage_) {
                        clear_storage(*reinterpret_cast<std::size_t*>(&tmp_msg->data_),
                                      static_cast<std::int32_t>(data_length) + tmp_msg->remain_);
                    }
                    return true;
                }, info->cc_id_, msg_id, remain, data, size)) {
                    return false;
                }
            }
            info->rd_waiter_.broadcast();
            return true;
        };
    }, h, data, size);
}
