Function mynewt::kernel::os::os_callout_init

pub unsafe extern "C" fn os_callout_init(
    cf: *mut os_callout, 
    evq: *mut os_eventq, 
    ev_cb: os_event_fn, 
    ev_arg: *mut c_void
)

Initialize a callout.

Callouts are used to schedule events in the future onto a task's event queue. Callout timers are scheduled using the os_callout_reset() function. When the timer expires, an event is posted to the event queue specified in os_callout_init(). The event argument given here is posted in the ev_arg field of that event.

• c: The callout to initialize
• evq: The event queue to post an OS_EVENT_T_TIMER event to
• timo_func: The function to call on this callout for the host task used to provide multiple timer events to a task (this can be NULL.)
• ev_arg: The argument to provide to the event when posting the timer.
