/*
The notification callback for when the application should be notified of a change to the device.
This callback is used for notifying the application of changes such as when the device has started,
stopped, rerouted or an interruption has occurred. Note that not all backends will post all
notification types. For example, some backends will perform automatic stream routing without any
kind of notification to the host program which means miniaudio will never know about it and will
never be able to fire the rerouted notification. You should keep this in mind when designing your
program.
The stopped notification will *not* get fired when a device is rerouted.
Parameters
----------
pNotification (in)
A pointer to a structure containing information about the event. Use the `pDevice` member of
this object to retrieve the relevant device. The `type` member can be used to discriminate
against each of the notification types.
Remarks
-------
Do not restart or uninitialize the device from the callback.
Not all notifications will be triggered by all backends, however the started and stopped events
should be reliable for all backends. Some backends do not have a good way to detect device
stoppages due to unplugging the device which may result in the stopped callback not getting
fired. This has been observed with at least one BSD variant.
The rerouted notification is fired *after* the reroute has occurred. The stopped notification will
*not* get fired when a device is rerouted. The following backends are known to do automatic stream
rerouting, but do not have a way to be notified of the change:
* DirectSound
The interruption notifications are used on mobile platforms for detecting when audio is interrupted
due to things like an incoming phone call. Currently this is only implemented on iOS. None of the
Android backends will report this notification.
