Re: [Discuss-gnuradio] QUESTION: Number of inputs to general_work

[Jonas Gacrama]

These are some of the input parameters of  gr_block::general_work() :

input_items     vector of pointers to the input items, one entry per input 
stream
output_items    vector of pointers to the output items, one entry per
output stream

Am I correct in understanding that the input_items CAN point to a
vector<float> type of inputs? I plan to implement two input channels
of vector<float> type. Therefore I plan to pass TWO POINTERS of
vector<float> type as "input_items" to general_work.

Note that the discussion on this website:
"http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html";
only used one
"channel" of inputs since it only took values from a single stream. I
plan to take TWO CHANNELS of inputs wherein each channel contains
10000 inputs.


By the way, the discussion in the above-mentioned site is not so
clear..... sorrry...
