zstack home 1.2.2a AF接收函数疑问(CC2530DB）

zcl.c文件中有一个zcl_event_loop（）函数：

uint16 zcl_event_loop( uint8 task_id, uint16 events )
{ ...

if ( *msgPtr == AF_INCOMING_MSG_CMD )
{
zcl_ProcessMessageMSG( (afIncomingMSGPacket_t *)msgPtr );  //AF数据接收处理函数

...
}

zcl_samplelight.c文件中有个 zclSampleLight_event_loop(  )函数：

两个event_loop(  )函数分别用来处理什么任务啊？有什么不同呀

    // The order in this table must be identical to the task initialization calls below in osalInitTask.
    const pTaskEventHandlerFn tasksArr[] = {
    macEventLoop,
    nwk_event_loop,
    Hal_ProcessEvent,
    #if defined( MT_TASK )
    MT_ProcessEvent,
    #endif
    APS_event_loop,
    #if defined ( ZIGBEE_FRAGMENTATION )
    APSF_ProcessEvent,
    #endif
    ZDApp_event_loop,
    #if defined ( ZIGBEE_FREQ_AGILITY ) || defined ( ZIGBEE_PANID_CONFLICT )
    ZDNwkMgr_event_loop,
    #endif
    zcl_event_loop,
    zclSampleLight_event_loop
    };

    你可以理解为是不同层次的消息，类似于TCP/IP的7层协议
