CallbackMidiDevicesOpenRemoved delegate

Previous pageReturn to chapter overviewNext page

Remarks

 

Callback delegate invoked from a secondary thread when a MIDI device, previously opened through the MidiDevices.Open method, is disconnected from the system after a manual removal.

 

In order to allow the component invoking this delegate at runtime, the container application must invoke the CallbackMidiDevicesOpenRemovedSet method passing the address of the callback function.

 

For further details about callback delegates see the How to synchronize the container application with the API tutorial.

For further details about the use of MIDI devices see the ClassMidiDevices class section and the How to manage MIDI devices tutorial.
