cant understand where the schedular uses the timer

[makouda]

I have the following code

 // Initialize timer module, making it use the scheduler
    APP_TIMER_APPSH_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE, true);


	//Create timer 1s
	err_code = app_timer_create(&timer_1s_id, APP_TIMER_MODE_REPEATED, timer_1s_timeout_handler);
    APP_ERROR_CHECK(err_code);

how the timer used the schedular , I cant find the code of the SDK the relation between the scheduler and the timer. in which part of the code of schedular the timer_1s_id is bind

The application timer can be used without the scheduler, and vise versa. If you use both the application timer and the scheduler, you should use APP_TIMER_APPSH_INIT() to initialize the application timer, as you do in your code. The code that makes the application timer use the scheduler are located in app_timer_appsh.c and app_timer_appsh.h, which you will find under components\libraries\timer\ in the SDK.

For a practical guide to the application timer I recommend you to walk through the Application Timer Tutorial. Then, if you need to use the scheduler, you should walk through the Scheduler Tutorial as well.

and when scheduler is used, where in the code the scheduler add the timer events to it's queue, this is my question
