kern/timer_call.h Kernel.framework

The timer_call system is responsible for manipulating timers that call callbacks at a given deadline (with or without some leeway for coalescing). Call timer_call_setup once on a timer_call structure to register the callback function and a context parameter that's passed to it (param0). To arm the timer to fire at a deadline, call any of the timer_call_enter functions. If the function used accepts a parameter, it will be passed to the callback function when it fires. If the timer needs to be cancelled (like if the timer_call has been armed but now needs to be deallocated), call timer_call_cancel.
