Re: [Discuss-gnuradio] Question about the "ninput_items"

   1.How did the system know how many items I can consume in a work call?

Because it's the one who supplies these -- hence, it knows how many exist!

  

   2.Do you means that every times call the block,the block will throw the ninput_items[0] items?

the work function *can* consume up to ninput_items[0] from input steam 0

     For example,the input steam 0 item is 1,2,3,4,5...  and the ninput_items[0]=2.

That's impossible. ninput_items says how many unconsumed there are.
So if ninput_items[0]==2, then input_items[0] can only be 1,2, undefined, undefined,undefined...

   3.I add two files before and after "Stream CRC 32" block respectively. Namely file1.dat and file2.dat.

You means file_sinks?

The type is "Byte".Can I use the read_char_binary.m in matlab to look at the data?

Yes.

Or use other m file provided by the gnuradio?Thank you.

It's just binary data. Interpretation by your Matlab programs is up to you!
