</p><p>Creating your own stream buffers for I/O can be remarkably easy.
If you are interested in doing so, we highly recommend two very
excellent books:

Addison-Wesley, who isn't paying us a cent for saying that, honest.

the fact that C++ may not, in fact, have anything to do with it?
</p><p>The rules for buffering can be a little odd, but they aren't any
different from those of C. (Maybe that's why they can be a bit
just those at the language/library level. Kernel buffers, disk
buffers, and the like will also have an effect. Inspecting and
changing those are system-dependent.
