void app_Key_Long_timer(int eid)
{
      
    app_t *curapp = GET_CURR_APP();
    static int key_time_2S = 0;
   
    if (eid == TIMER_UNREGISTER) {
        key_time_2S = 0;
        return;
    }
    key_time_2S++;
    if (key_time_2S == 2) {
        app_timer_unregister(TIMER_1HZ, app_Key_Long_timer);
        key_long_flag = 1;        
        key_time_2S = 0;   
        }
}

看函数原型，这个整型eid是一个传入app_Key_Long_timer函数的一个参数

app_timer_unregister(TIMER_1HZ, app_Key_Long_timer);
这里没有给eid参数啊

void app_lcd_power_timer(int eid)
{
    app_t *curapp = GET_CURR_APP();
    static int time_300S = 30;//300s
    static int time_120S = 12;//120s
    static int time_30S = 3;//30s
    if (eid == TIMER_UNREGISTER) {
        time_30S = 3;
        time_120S = 12;
        time_300S = 30;
        return;
    }
   
    if(usb_connect)
        return;
        
    if (sys_status.pref->power_Lcd_off == SYSSET_LCD_OFF_30S)
    {
        time_30S--;
        if (time_30S==0)
        {
            time_30S = 3;
            app_set_backlight(0);
            AutoLcdOffFlag=1;
        }
    }
    else if (sys_status.pref->power_Lcd_off == SYSSET_LCD_OFF_120S)
    {
        time_120S--;
        if (time_120S==0)
        {
            time_120S = 12;
            app_set_backlight(0);
            AutoLcdOffFlag =1;
        }
    }
    else if (sys_status.pref->power_Lcd_off == SYSSET_LCD_OFF_300S)
    {
        time_300S--;
        if (time_300S==0)
        {
            time_300S = 30;
            app_set_backlight(0);
            AutoLcdOffFlag =1;
        }
    }
}
app_timer_unregister(TIMER_CHECK, app_lcd_power_timer);
看这样的例子好多啊

神对话，俺表示真看不懂……

我也看不懂，所以才发出来请高手帮忙，但是确实是代码没问题。这是安霸A2平台里的代码

int app_timer_unregister(int id, timer_handler hdlr)
{
    int i, found;
    app_timer_t *cur;

    if (id >= MAX_TIMER) {
        return -1;
    }

    if (hdlr == NULL) {
        return -1;
    }

    cur = &(timer[id]);

    if (cur->num == 0) {
        return -1;
    }

    found = 0;
    for (i=0; (i<MAX_TIMER_HANDLER)&&(!found); i++) {
        if (hdlr == cur->handler[i]) {
            found = 1;
            cur->handler[i] = NULL;
            cur->num--;
            hdlr(TIMER_UNREGISTER);
        }
    }

    if (found) {
        if (cur->num == 0) {
            AMP_clr_timer(id);
        }
    }

    return 0;
}

知道啥是函数不

不是太清楚，请指教
