Is there a replacement for printf in a kernel

[EmmanuelMess]

I think I missed how to print from a kernel, so I have just been using printf from cuda. Is there a way to use something like streams?

That would be a device-side facility, while this is a host-side library. I had toyed with a cout-like stream in my cuda-kat library, but the implementation I had was incredibly slow to compile. For now, we have my additionals for this issue, which provides more of the C standard library's printf functionality, but can also serve as a basis for a stream-like facility; or better yet, an std::format / fmt::format-like function.

Are you sure you like the former rather than the latter?

I would be happy with something similar to "ROS_*_STREAM" functions, those are used like this: ROS_ERROR_STREAM("bla" << 8)

@EmmanuelMess : Again, that would be a cuda-kat request. But I'm not familiar with these "ROS" functions; plus, that looks like macro-use, which I try to avoid.
