This doesn't mean that the internal representation is null- terminated. You're not guaranteed anything about the implementation of C++ strings, although you are guaranteed some big-O things about performance. This goes for all the STL classes, I believe (can someone check me on that?).

std::basic_string::c_str

const charT*
c_str () const;
const charT*
data () const;
Return a pointer to the initial element of an array whose first size () elements are copies of the elements in this string. A traits::eos () element is appended to the end. The elements of the array may not be altered, and the returned pointer is only valid until a non-const member function of this string is called. If size() is zero, the data () function returns a NULL pointer.
