Re: [Discuss-gnuradio] Code Reuse Question

[Marcus Müller]

Generate a general_block. Copy the content of head_impl.cc 's work() method to the general_work method. don't forget the private variables from head.h and the initialization of those in the constructor.
Replace the "return -1;" by "return 0" to make the block stop producing samples after it's done it's job; before the final "return n; " add a "consume_each(n);".

Best regards,
Marcus

I don't want the flowgraph to stop. I just want to store a set number but leave the flowgraph running.

You can use a head block inline (already in core).

Hello,

I want to add an additional parameter to the existing file sink block that lets the user tell it how many items to save to file. This amounts to adding a few lines to the existing file sink work function.

What's the smartest way to do this? What I would do currently is create a new block, copy and paste the existing file sink code to my new block and add the few lines of code to change it. Is there a smarter way?
