There are two posix functions ("truncate" and "ftruncate") which might do what you need.
It doesn't look like these functions exist for MSVC users. So it seems there is no portable way to change the size of a file. Beman, would this make a good addition to the filesystem library?
MSVC offers "_chsize_s" for such a task, which (of course), is not available for Linux...
The Windows API version for this is called SetEndOfFile. This is a truncating type function. I would use this function unless there is really a need to use the runtime library version. -- Bill --
