[PATCH 6/6] winealsa: Move the midi event handlers to the unixlib.
by Huw Davies March 24, 2022

March 24, 2022

The MIM_DATA and MIM_LONGDATA notifications are sent via the notification thread. The midi_handle_event syscall is temporary.

[PATCH 4/6] winealsa: Introduce a notification thread.
by Huw Davies March 24, 2022

March 24, 2022

Currently the thread just blocks until told to quit by midi_release. Eventually this thread will dispatch the MIM_DATA and MIM_LONGDATA notifications.
