alarm_pool_remaining_alarm_time_us() function

the alarm_pool containing the alarm

the alarm

Cancel an alarm

Add an alarm callback to be called at a specific time Generally the callback is called as soon as possible after the time specified from an IRQ handler on the core the alarm pool was created on. If the callback is in the past or happens before the alarm setup could be completed, then this method will optionally call the callback itself and then return a return code to indicate that the target time has passed.

Return the core number the alarm pool was initialized on (and hence callbacks are called on)

Add a repeating timer that is called repeatedly at the specified interval in microseconds Generally the callback is called as soon as possible after the time specified from an IRQ handler on the core the alarm pool was created on. If the callback is in the past or happens before the alarm setup could be completed, then this method will optionally call the callback itself and then return a return code to indicate that the target time has passed.

Add an alarm callback to be called at or after a specific time The callback is called as soon as possible after the time specified from an IRQ handler on the core the alarm pool was created on. Unlike alarm_pool_add_alarm_at, this method guarantees to call the callback from that core even if the time is during this method call or in the past.

Destroy the alarm pool, cancelling all alarms and freeing up the underlying timer_alarm

Return the time remaining before the next trigger of an alarm

Return the timer alarm used by an alarm pool

Add an alarm callback to be called after a delay specified in microseconds Generally the callback is called as soon as possible after the time specified from an IRQ handler on the core the alarm pool was created on. If the callback is in the past or happens before the alarm setup could be completed, then this method will optionally call the callback itself and then return a return code to indicate that the target time has passed.

Add an alarm callback to be called after a delay specified in milliseconds Generally the callback is called as soon as possible after the time specified from an IRQ handler on the core the alarm pool was created on. If the callback is in the past or happens before the alarm setup could be completed, then this method will optionally call the callback itself and then return a return code to indicate that the target time has passed.
