Hi all,
I'm putting together an inprocess client (as it was the lowest hanging fruit), but
I'd like to output log messages, I note that outputting to stdout/stderr doesn't
seem to work.
Is there any API into which I can hook my logging framework output ?
Regards

Just for additional information, I have an .so called jackmyplug.so, in
/home/pi/jackmyplug.so (exporting jack_initialize/jack_finish), so I load it with:
pi@realtimepi:~ $ jack_load myplug /home/pi/jackmyplug.so
Jack: JackClient::SetupDriverSync driver sem in flush mode
Jack: JackLinuxFutex::Connect name = jack_sem.1000_default_jack_load
Jack: Clock source : system clock via clock_gettime
Jack: JackLibClient::Open name = jack_load refnum = 2
could not load /home/pi/jackmyplug.so, intclient = 0 status = 0x 1
Ideas ?

pi@realtimepi:~ $ jack_load myplug
/home/pi/jackmyplug.so
Jack: JackClient::SetupDriverSync driver sem in flush mode
Jack: JackLinuxFutex::Connect name = jack_sem.1000_default_jack_load
Jack: Clock source : system clock via clock_gettime
Jack: JackLibClient::Open name = jack_load refnum = 2
could not load /home/pi/jackmyplug.so, intclient = 0 status = 0x 1
Ok, ok, slowly getting there, I've now copied the jackmyplug to /usr/local/lib/jack
folder, and do:
pi@realtimepi:~ $ jack_load jackmyplug
Jack: JackClient::SetupDriverSync driver sem in flush mode
Jack: JackLinuxFutex::Connect name = jack_sem.1000_default_jack_load
Jack: Clock source : system clock via clock_gettime
Jack: JackLibClient::Open name = jack_load refnum = 2
Jack: JackClient::ClientNotify ref = 3 name = jackmyplug notify = 0
Jack: JackClient::AddClient name = jackmyplug, ref = 3
Jack: JackLinuxFutex::Connect name = jack_sem.1000_default_jackmyplug
Cannot read socket fd = 3 err = No such file or directory
Cannot read socket fd = 5 err = Success

Upon which the server stopped streaming. Does the above look ok ? None of my log outputs
can been seen...

The internal client runs inside the JACK process, that's where it'll
log, too, I guess.
Try to start jackd in a terminal and I'd expect your client's logs to
show up there, not in the terminal where you jack_load'ed it in the
first place.
