It's fine to take this, and I would take it as is for now. But we can extend the rawmidi somehow to deal with such an error, too. Maybe just having "error" flag in the rawmidi runtime and adding a helper function to set the error and stop the stream should work easily. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
