So at the input of the C++ we are giving vector_source_c() and then input output signatures are sizeof(gr_complex). The work function is taking noutput_items and returning noutput_items. We understand now that because we have used set_output_multiple(fft_length) in the constructor, the noutput_items is fixed at the fft_length and then work function is being called.
The noutput_items could be fft_length or multiple of fft_length.Says fft_length is 8192, then noutput_items could be either 8192, 16384 or 24576 etc, determined by the scheduler.
If you only get noutput_items equals to 8192, that could be due to the number of input elements available is less than 16384.
However one small doubt,when we print value of noutput_items in C++ program inside the work function ,the print statement is executed twice for any fft_length we use. Is this correct? It should only print once the value of noutput_items if i am right.
If the print statement is executed twice, that means the work() function is invoked twice.It could be something wrong with your code, let's show your code here.
