mmap(2) + memcpy(3) ? Boost::Iostreams already has a mapped_file Source.
If you read it into memory and write it out, it could fail in tight memory situations.
I’m looking for something like copyfile(const char* from, const char* to) or copyfile(path from, path to), preferably something in Boost if it has it. If you find it for me, it’s more likely I’ll get to implementing it.

As for the file copy, why add to the boost dependency? I for one would love to get a core lib with very little deps.
We require Boost for JSON and a dozen things replacing dependencies on wxWidgets. Boost is good, portable stuff, we should not shy away from it.
