Hello,
I'm trying to use jack_set_xrun_callback to be notified in my
application of eventual xrun.
in the documentation of the function I see a note: that 'this function
cannot be called while the client is activated'.
Does it mean that my client must call jack_set_xrun_callback before
being activated
Yes. First set the callback, and only later call jack_activate().
Two tiny jack clients which may come in handy:
* jackxrun: report x-runs on the command line
* busyjack: create artificial load
http://gareus.org/gitweb/?p=jackfreqd.git;a=tree;f=tools;
gcc -o jackxrun jackxrun.c -ljack
gcc -o busyjack busyjack.c -ljack
./jackxrun # reports xruns in the terminal
./busyjack 90 # will ramp things up to 90% DSP load (default is 50)
It can be used to create x-runs, yet it's not the same as a x-run from hw.
[..]
It says return 0 on success. Does it mean the callback
must succeed.
Your callback function must return 0.
Cheers!
