Use a standard pointer, and malloc/calloc/whateveralloc.
You can allocate events directly on the stack (without pointers), too.

The event lives in some internal buffer managed by the ALSA library.
Simply don't do anything to free it.

The event buffer may be reused by the next snd_seq_event_input() call.
