Hello list,
I need some advice on the ALSA sequencer interface. In particular I'd
like to know if the following code can be safely used inside a real-time
audio thread, i.e. is it guaranteed not to block ?
As far as I've been able to find out, it should be safe.
snd_seq_event_t *E;
if (snd_seq_event_input_pending (midi_seqh, 1))
{
do
{
snd_seq_event_input (midi_seqh, &E);
// handle event E
}
while (snd_seq_event_input_pending (midi_seqh, 0));
}
