Need to move from formatted string to binary buffers

Question

I am using formatted std::string to store my intermediate buffers before dumping them in a file.

Now I want to write my intermediate data in binary buffers as I want to dump my file in binary format. Which type do I need to use for these binary buffers.

Take note that these intermediate records are formatted data in a string. By formatted data, I mean string made by call of sprintf with %s,%d etc.
