Hi,
I have a program with some (p)threads, and a jack ringbuffer. One
thread is writing to the ringbuffer, and another is reading from it.
The question is: is it (thread-)safe to have a _third_ thread that
looks at the ringbuffer via jack_ringbuffer_read_space() at random
times to determine how much data is in the ringbuffer? This third
thread does not actually read nor write any data to/from the
ringbuffer, just wants to know the amount of data in it.
So far I didn't see any crashes/lockups, is it really safe to do this
or just my dirty luck? :)
Thanks,
As long as the third thread really never reads/writes any data from the ringbuffer it
should be ok afaik.. But what is the purpose of that third thread? Do maybe the results of
this third thread have side effects on the other two threads? Depending on what you do
with the fill information of the ringbuffer you might get unexpected results..
