Hi,
Thank you in advance.I have a question about the "ninput_items".I find the meaning of it is "vector of items available on all input buffers".
When I read the source code of "crc32_bb_impl.cc",I see the code below,
"
int
65 crc32_bb_impl::work (int noutput_items,
66 gr_vector_int &ninput_items,
67 gr_vector_const_void_star &input_items,
68 gr_vector_void_star &output_items)
69 {
70 const unsigned char *in = (const unsigned char *) input_items[0];
71 unsigned char *out = (unsigned char *) output_items[0];
72 long packet_length = ninput_items[0];
"
I think the ninput_items[0]=1,because the item input is 1 every times.But when I write the code "std::cout<<ninput_items[0]<<std::endl;",It display the packet_length.I think the ninput_items[0]=1 no matter what pack_length is.Why I'm wrong?
Thank you.
Best regards,
