Concatenate streams in C++

I am using C++.  I have a stream that comes from a socket.  I want to create a new stream which concatenates the socket stream to a pre-existing stream.

Is there a standard method of doing this in C++?

I guess you might as well just repeatedly extract from the input stream and insert into the output stream until the input stream runs out. As I recall, if the stream is binary, you can just extract and insert chars and get the result you expect. Doesn't get much simpler than that.

(For a more "standard" approach, you're probably supposed to use ostream_iterator and istream_iterator, maybe in conjunction with std::copy. But since there's no such thing as an "end" for the "sequence" implied by the istream_iterator, you can't do this...)

I think the OP has solved his problem now but for information, it is possible to create an end iterator for istream_iterator : it is the default constructor.

So...
std::istream_iterator itBegin(istreamSource);
std::istream_iterator itEnd;
std::ostream_iterator itOutput(ostreamDestination);

std::copy(itBegin, itEnd, itOutput);
