## Detailed Description

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

## Enumeration Type Documentation

anonymous enum

  | Enumerator:
  Init |
  Run |
  Exit |

## 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 main | ( | int | argc,
|  | char * | argv[]
| ) |

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 follows a simple rule: when the JACK transport is running, copy the input port to the output. When it stops, exit.

## Variable Documentation
