temporary file stream

Question

I'd like to create a temporary file stream. Is there a c++ equivalent to C's tmpfile() function.

If not, how would I create one?

What platform ? If on unix, this is a duplicate of http://stackoverflow.com/questions/499636/c-how-to-create-a-stdofstream-to-a-temp-file . — Alexandre C., Apr 07 '11 at 15:42

You could check whether your implementation offers a std::fstream constructor that takes a file descriptor, and if so use fileno to get the fd from the FILE* returned by tmpfile(). But the C++ standard doesn't guarantee that constructor.
