[Libevent-users] Wait until the loop thread processes all the data?

[Egor Tensin <egor@xxxxxxxx>]

Hello,

Hopefully you can help me with a libevent issue that I'm stuck on. I
have two threads, one of which produces data, and the other runs
event_base_dispatch (receiving the data from the first thread,
processing it and sending it somewhere else). They communicate using a
pair of bufferevents (over a local socket pair). The issue is, the
first thread might be done with producing the data, program
termination being the next logical step. But I want to wait for the
second thread to 1) receive _all_ the data the first thread sent, 2)
process it and 3) send it to the final destination. I can't figure out
how to accomplish that, because if I call event_base_loopexit after
the first thread stops, it looks like the second thread exits right
after executing the current round of callbacks, discarding the latest
data that might have been sent by the first thread. Can somebody
please explain to me how to fix this? I can set a random timeout for
event_base_loopexit, but this is unreliable, isn't it?

Regards,
Egor Tensin.
