How Timer calls a callback function in C


Forum Post 1 Answer How Timer calls a callback function in C

I would like to implement a scheduler.

The scheduler would be assigned multiple jobs and will configure the time interval when the job/callback function should called...

I could say, Callback-function_1 should be called after 20 secs and callback-function_2 should be called after 30 secs like that....

we can assume, from the start time, after 20 secs the first callback-function would be called...

How all these callback functions are put into a queue (the one which is going to be called soon has to be first...) and how they have been called ? How the timer invokes those callback-functions ? How do we pass an arguments to the callback-functions in this case...?

Suppose your application is using the timer functionlity and you want the application to be notified periodically or aperiodically you can have callback functions at handy.
Pass a function pointer of the application code to timer,so that it can be called accordingly.It is called registering the function with timer.
