Create a streambuf from const char*?

I want to make a read-only buffer from raw data I have so that I can call boost::asio::buffer_copy several times in a row without worrying about maintaining the right offset and length.

Is the streambuf the right solutions in this case? If it is, how can I create streambuf from const char* raw data without copying it?

Since you're using Boost, you can use Boost.Iostreams.

#include <boost/iostreams/device/array.hpp>
#include <boost/iostreams/stream_buffer.hpp>

int main()
{
    namespace bio = boost::iostreams;
    const char source[] = "hello world";
    bio::stream_buffer<bio::array_source>  stream_buffer(source, sizeof(source));
}
