Custom C++ stream for custom type

I've read about custom streams for C++ but it seems that generally people inherit from std::streambuf, std::istream, and std::ostream. By inspecting those type's declarations it becomes clear that these are meant for characters:

typedef basic_streambuf<char>        streambuf;

The docs confirm this:

Input stream objects can read and interpret input from sequences of characters.

Obviously, that makes sense. I'm wondering what would be the correct way of implementing a stream for other types. I do not want to allow text but other forms of binary input/output (I have specific formats). The obvious step seems to be to inherit the basic variants of the above (basic_streambuf, basic_istream, and basic_ostream) and use whatever type I see fit as the template parameter. I failed to find confirmation that this would be the right procedure. So, is it?
