the code is a bit cleaner that way.
For a new audio application I need to code a JACK
client with C++. So
far I did it only with C and have a problem with giving the pointer to
the callback process function, which is a method now. So what is the
best performing solution? Is a delegate function a good idea, being
static and triggering the method in the objectinstance?
No idea what the best solution might be, but here's an approach I've used...
class AudioOutputJACK
{
public:
[ ... ]
private:
static int ProcessJackCallback(jack_nframes_t nframes, void* arg);
}
