## Detailed Description

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

## Function Documentation

void jack_shutdown | ( | void * | arg | ) |

JACK calls this shutdown_callback if the server ever shuts down or decides to disconnect the client.

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)
