Hi Haaris,

as said in my stackoverflow response [1], it's really not a good idea to modify file_sink – you really just want modify the item stream, so do that in a block you add before your file_sink.

If you've installed GNU Radio as binary package, then the source code will not be anywhere – if you want to modify GNU Radio, you'd have to build it from source yourself, and in that case, you'd probably know where the source code was :D

Best regards,

Hi Marcus,

Thanks a lot for the reply.
The screen shot of the flow graph is present below.


One more thing is that where in ubuntu is file_sink.cc or the C++ files of blocks present?
I searched the whole computer for '.cc' and found no .cc gnu radio block file.
I think I can easily change the C++ code to solve this problem.
Please don't recommend adding a new block, because I have tried that 2 or 3 times and it just does not work.
There are different errors everytime I try to add a new block, sometimes gnu radio just doesn't pick it up etc.
Moreover there is also not much time left now, before my demo.

Thanks once again for your time.
