Hi,

I am trying to build a model 3 motor driver for a manipulator, that is
interfaced by a vendor-DLL on windows. I can load the the DLL within the
motor driver class library, however this library needs to be explicitly
unloaded (using FreeLibrary) before exiting the program, otherwise it
crashes on exit. Therefore, I am looking for a way to invoke this unload
function upon exit of the ioc, i.e. when "exit" is called in the ioc or
it is stopped otherwhise. I tried building a destructor for my motor
driver class, but this does not ever seem to be invoked. Is there any
proper way of doing this?

Best regards,

Laurenz
