Thanks Mennetau, nice answer.
One more though. What is the difference between fopen and open?
Why is there an fopen call when open seems to do it all, and even
better? Is fopen better buffered, or what?
fopen is a higher level call that gives you access to higher level
calls
such as fgets/fgetws (get string/wstrinf from afile) that you
don"t get with read.
Anyhow, for my case, I don't want any buffering.
Do you have any idea how I can ask the OS what is it's preferred
file I/O read/write size?
perhaps with sysctl. For example, you can get the software page
size and any I/O operation is a multiple of that value
Unfortunately, that just tells me 4096, which to be honest, is a
kind of sucky buffer size ;)
It's one page, which sounds like a pretty good size to avoid hitting
multiple page boundaries :)
