ostream_iterator for Binary Output

Question

I want to be able to use an ostream_iterator to stream to a binary file. But the ostream_iterator uses a FormattedOuputFunction so it will write ASCII, not binary:<

Answer 1

ostreambuf_iterator is more appropriate than ostream_iterator. It's much lighter weight and it does no formatting. It takes a template argument for the character type, so the only choice compatible with most streams is std::ostream_iterator< char >.

Be sure to open the stream in binary mode. The standard stream buffers, by the way, are never opened in binary mode.
