Re: [Discuss-gnuradio] Stop GRC flow graph after defined time

That run-to-completion method has never failed me; the only
explanation for that kind of behavior would be if your flowgraph
employed message passing. Is that the case?

Anyway, to make GNU Radio stop the flowgraph when your source is
empty, you shouldn't call stop().
The source's work() method returns the number of produced items. A
zero there should make the flowgraph realize you're done. If you want
it explicitely (and right), let the work method return WORK_DONE (==-1).

Greetings,
Marcus
