title: Does there exist a type similar to std::string (i.e., holding blobs of data of arbitrary length) that does not use the null terminator?
body: <p>I use <code>std::string</code> to hold arbitrary blobs of binary data. It works this way, but is slightly inefficient as it needs to add the null terminator to the end of the blob. (C++11 spec is that <code>c_str()</code> and <code>data()</code> are the same, and return a pointer to a blob with a null terminator at the end.) Is there a better type to use, that still supports common operations (copy constructor, assignment operator, etc)?</p>
