Re: Using sound for object tracking feedback

It runs ( generating PCM/tone in the background) and exports a function call API to change the tone. I think this should set you on the right path. In fact, for a preliminary prototype -- with no beeping -- it probably fulfills the basic tone generation functionality. What is left to figure out is h...

Re: Using sound for object tracking feedback

Threading is one way of multitasking. Event based I/O (poll(2), select(2)) or asynchronous notification via signals are alternatives used to add multitasking capabilities to single threaded applications. It depends on the situation.
