Under windows you do that as follows:

(1) Create a File with CreateFile
(2) You move the file pointer to the desired size with SetFilePointerEx
(3) You set the end of the file with SetEndOfFile

You can find the documentation for those APIs in the documentation from
Microsoft.

Which works for VisualC, right?

Cue for a debate (or even a flame war). I haven't taken a census, but
I'm far from convinced that the majority here have experience of
developing on Windows.

SCO and Linux for me. I've been working on an embedded MC860-based
platform before.

It seems to me that Hans is in danger of breaking at least the 10th of
Spencer's commandment <http://www.lysator.liu.se/c/ten-

No, it works for any compiler running windows, those are APIs of
the operating system

Yes, but there is a vocal group of people that say that windows is the
empire of evil, etc.

I develop under windows and iphone/Apple. Lately, I got bored with
windows and changed to Apple, a great platform. It makes Unix
shine, it is a very good combination of a good GUI with a powerful
Unix system. Linux folks could learn something from them, after
more than a decade their system is as "usable" as SCO + Xwindows
was.

But surely I know something about windows, see my other answer
in this thread.

I use Windows only rarely - mostly when someone insists on using
Microsoft Word documents which rely upon features that Sun's OpenOffice
doesn't fully support when saving in M$ Word format. I've never written
a program for it; the closest I came was programs written for DOS, and
the last time I did that was 15 years ago.

Majority here or the majority of commercial developers? (i.e. leaving
aside home/hobby use) Then the vast majority will be developing on
Windows

When was the last time you gave any linux distro a try?
