Hm, I am thinking about how to make use of snd_seq_remove_events in my
application. It's sad that I cannot find out what events I have actually
removed. It would be bad if e.g. a NoteOff gets lost and thus a tone is
played forever. It would be great if I could find out pending events in
the queue (in the kernel space). Then I could fetch them and re-send them
immediately, when the user stops my sequencer.
Unfortunately snd_seq_extract_output only fetches events from the user
buffer. Is there a snd_seq_extract_output for drained messages?
