Re: [Discuss-gnuradio] return value of gr::block::general_work

[Dave NotTelling]

I found in the docs that general_work only supports outputting the same number of samples to each output port (https://github.com/gnuradio/gnuradio/blob/master/gnuradio-runtime/include/gnuradio/block.h#L47-L49) but the produce method seems to tell otherwise (https://github.com/gnuradio/gnuradio/blob/master/gnuradio-runtime/include/gnuradio/block.h#L241-L248) and even has its own return flag for general_work.  So, question is: can general_work output different numbers of samples to each output port by use of the produce() function and returning -2 in general_work?

Hi Weihan,

For any block, the noutput_items is just a scalar - meaning "number of items actually written to each output stream" is same for all the output ports. The buffer size of all output ports are the same.

Hi,

From the manual it says this number is "number of items actually written to each output stream". But I'm a bit confused that if we have a block with multiple output ports, then what does the return value mean? Please help, thanks.

Regards,

Weihan
