C++ & Boost: How do I convert a dynamic bitset to a string?

Question

So, the documentation says this:

template <typename Char, typename Traits, typename Block, typename Alloc>
basic_ostream<Char, Traits>&
operator<<(basic_ostream<Char, Traits>& os, const dynamic_bitset<Block, Alloc>& b)

Effects: Inserts a textual representation of b into the stream os (highest bit first). Informally, the output is the same as doing

std::basic_string<Char, Traits> s;
boost::to_string(x, s):
os << s;

which I don't understand at all.

Here is what I have

boost::dynamic_bitset<> bit_value(Config::HASH_WIDTH_IN_BITS, hash_value);
string buffer = bit_value.to_string();

Which doesn't work, cause dynamic bitset has no member .to_string();

to_string is a free function in the boost namespace, not a member function.

boost::dynamic_bitset<> bit_value(Config::HASH_WIDTH_IN_BITS, hash_value);
string buffer;
to_string(bit_value, buffer);
// here buffer contains the string representation of bit_value.

Which header should be included?

boost::dynamic_bitset is defined in boost/dynamic_bitset.hpp
