Best way to see file's size

Microsoft also has integer-64 versions of the fseek/ftell functions.

You mean _teilli64() - that's not a version of ftell() - it's a version of the linux tell() function.

But I also realized that fsetpos is not analogous to fseek in that it takes an absolute file position, so there's no way to say "move to 0 bytes from the end of the file".

No, I mean _ftelli64 and _fseeki64.

Ah, yes, found those now - somehow, when I was looking at fsetpos, it didn't have _fseeki64. Googling for that specifically does however show it up.

Such systems still have a significant market share. The real world is like that sometimes: the technically best or even right is not necessarily what survives.

Just out of curiosity, what systems are those? I just can't understand how you would be able to for example build a working database system with a seek function that "doesn't always work". Or are we talking only on certain types of media (say CD-ROM or tape)?
