The USRP sink is basically the gnuradio device driver for the USRP. Look at the USRP library code to see how it actually sends the raw data. It accesses the USRP through the USRP device filesystem. It's not simply just writing something to /dev/usrp..

I know that it writes to the USRP sink through tranmit_path.py. I want to know how is this sink referenced as. Is it a device file with a name such as /dev/... etc or is it referenced as something else. I looked at the whole code and also the programs that are referred to in the code but didn't find a clear answer. When we call send_pkt() function where is the payload written to (of course USRP_Sink) but what is it in terms of a file path. I hope I put my question in clear words. If I am wrong or misunderstood something then please correct me.
