Talk:Truncate a file

So just to be sure, if the actual file size is smaller than the given truncated size, it's an error? It doesn't just leave the file alone? --Mwn3d 14:09, 19 July 2011 (UTC)

POSIX truncate() and ftruncate() extends the file if specified size is larger than original. It's convenient when you want to reserve some disk space. --Ledrug 14:25, 19 July 2011 (UTC)

Assumes unix

It's pretty clear that this task assumes unix file system semantics. So, can we ignore other operating systems in this task? --Rdm 14:33, 19 July 2011 (UTC)
