Tell the Jack server to call @a process_callback whenever there is
work be done, passing @a arg as the second argument.
The code in the supplied function must be suitable for real-time
execution. That means that it cannot call functions that might
block for a long time. This includes malloc, free, printf,
pthread_mutex_lock, sleep, wait, poll, select, pthread_join,
pthread_cond_wait, etc, etc. See
http://jackit.sourceforge.net/docs/design/design.html#SECTION00411000000000000000
for more information.
NOTE: this function cannot be called while the client is activated
(after jack_activate has been called.)
@return 0 on success, otherwise a non-zero error code.
