Detailed Description

This simple client demonstrates the most basic features of JACK as they would be used by many applications.

Function Documentation

jack_shutdown()

void jack_shutdown

(

process()

int process	(	jack_nframes_t	nframes,
		void *	arg
	)

The process callback for this JACK application is called in a special realtime thread once for each audio cycle.

This client does nothing more than copy data from its input port to its output port. It will exit when stopped by the user (e.g. using Ctrl-C on a unix-ish operating system)
