Expand description

Specifies callbacks for JACK.

Provided methods

Called just once after the creation of the thread in which all other callbacks will be handled.

It does not need to be suitable for real-time execution.

Called when the JACK server shuts down the client thread. The function must be written as if it were an asynchronous POSIX signal handler — use only async-safe functions, and remember that it is executed from another thread. A typical funcion might set a flag or write to a pipe so that the rest of the application knows that the JACK client thread has shut down.

Called whenever “freewheel” mode is entered or leaving.

Called whenever the system sample rate changes.

Called whenever a client is registered or unregistered

Called whenever a port is registered or unregistered

Called whenever a port is renamed.

Called whenever ports are connected/disconnected to/from each other.

Called whenever the processing graph is reordered.

Called whenever an xrun occurs.

An xrun is a buffer under or over run, which means some data has been missed.
