bluez 事件 联系

一直不知道 事件是怎么触发的.事件触发回调

觉得很神奇.很迷糊.
其实bluez不能单独的看,也要在 内核中看代码

文件src/adapter.c  (bluez)
...
    mgmt_register(adapter->mgmt, MGMT_EV_CONNECT_FAILED,
                        adapter->dev_id,
                        connect_failed_callback,
                        adapter, NULL);
                               
    mgmt_register(adapter->mgmt, MGMT_EV_DEVICE_UNPAIRED,
                        adapter->dev_id,
                        unpaired_callback,
                        adapter, NULL);
                               
    mgmt_register(adapter->mgmt, MGMT_EV_AUTH_FAILED,
                        adapter->dev_id,
                        auth_failed_callback,
                        adapter, NULL);                                                                                                                                       
                               
    mgmt_register(adapter->mgmt, MGMT_EV_NEW_LINK_KEY,
                        adapter->dev_id,
                        new_link_key_callback,
                        adapter, NULL);

有没有觉得似曾相识.
好了可以接着看了.
