Well, I think I used io_signature correctly. And, as I am using gr_sync_block, I dont need to worry about forecast, set_output_multiple or gr_sync_decimator. (I hope this understanding is correct?!)
I have read the " how to write a block" and followed what's in there, but if you guide me to better documentation, I will be very grateful.
