[Boost-users] [filesystem] how to set a file size?

Forgive me for the n00b-ish (and slightly offtopic) question, but is 
there any way in standard C++ or in Boost.Filesystem to truncate a file 
to a particular size? With std::ofstream, I can either truncate a file 
on open to 0 size, or else open it in overwrite mode and scribble over 
it, but when I'm done, I don't seem to have a way of saying, "The end of 
the file is now *here*." Is that right? And if so, does Boost.Filesystem 
have an API for this?

Thanks,
