[Jack-Devel] jack midi event reserve vs. write

Dear All,

What exactly is the difference between *jack_midi_event_reserve* and 
*jack_midi_event_write* ?
In particular, if I call *jack_midi_event_write*, does it actually copy 
the data from the buffer, which I provide?
Or does it use that same buffer.

Another question is how can I send midi events generated from GUI, 
(which does not run in the audio callback)?
My guess is to cache them somewhere and transmit them inside the callback?
Am I guessing correctly?

Cheers,

Robert
