Re: [Discuss-gnuradio] Terminating flowgraph inside

[Marcus Müller]

Hi Nemanja,

What happens when arbitrary block in the middle of the flowgraph returns -1?

That block is set to the DONE state. After that, all output that still can be processed is processed, successively setting the downstream blocks to an "don't call me, there can be no input" state.
After that, the top_block.wait() call returns.

You probably want to have a look at Tom's presentation linked in[1].

is there any way that block inside a flowgraph terminate that flowgraph should stop.

Well, returning WORK_DONE==-1, but you've already figured that out, so my guess is you want something else; would you mind elaborating on your problem?

Best regards,
Marcus

Hello again,

is there any way that block inside a flowgraph terminate that flowgraph should stop. Something like when source block returns -1 from work function.

What happens when arbitrary block in the middle of the flowgraph returns -1?
