Function Documentation

void jack_free ( void *  ptr)

The free function to be used on memory returned by jack_port_get_connections, jack_port_get_all_connections and jack_get_ports functions. This is MANDATORY on Windows when otherwise all nasty runtime version related crashes can occur. Developers are strongly encouraged to use this function instead of the standard "free" function in new code.

int jack_is_realtime ( jack_client_t client)
Parameters:
clientpointer to JACK client structure.

Check if the JACK subsystem is running with -R (--realtime).

Returns:
1 if JACK is running realtime, 0 otherwise
