I have been doing some coding help on an audiounit plugin and I have
noticed that it and virtually all Music Device AudioUnits leave their
executable open after the component has been closed. The one notable
exception appears to be the DLS MusicDevice. Which leads to my
question. What is a Music Device (or other AU) plug-in supposed to do
to ensure that it's executable file is closed in the host after the
component is closed?
Here is an example of a path to a fictional plugin's file left open:
/Library/Audio/Plug-Ins/Components/pluginnamehere.component/Contents/
MacOS/pluginnamehere
Note that I have been checking the files left open using Activity
Monitor's 'open files and ports' tab and I have tried this test with
AULab, my host, Metro, and AudioUnitHosting. I am running OS X 10.5.3
(in case it is OS related).
As I side not it would be great if AUVal posted nasty warnings if
files were left open.
Thanks,
Jeremy
