JackXrunCallback not called

[Benoît Rouits]

hello list,

First of all, thanks for jackd, and the good doxygen documentation.

I am writing a very small jackd launcher and monitor application in
gtk+. There is a missing from my part on my client: jackd starts, and
reports xruns on stderr, but my xrun callback (of type JackXrunCallback)
is not called, though i registerd it with jack_set_xrun_callback(..). My
client do not treat sound, but only monitors jackd (no ports, so). Do
have i to use jack_port_request_monitor () on system in and out ports ?
how then to get them ? Thanks for any quick hint. Sorry to bother with
such a question.

AFAICS non RT callback are only called after jack_activate API has  
been used.
