Create a new modifiable buffer from a contiguous container.
template< typename T> mutable_buffer buffer( T & data, typename constraint< is_contiguous_iterator< typename T::iterator >::value, defaulted_constraint >::type = defaulted_constraint(), typename constraint< !is_convertible< T, const_buffer >::value, defaulted_constraint >::type = defaulted_constraint(), typename constraint< !is_convertible< T, mutable_buffer >::value, defaulted_constraint >::type = defaulted_constraint(), typename constraint< !is_const< typename remove_reference< typename std::iterator_traits< typename T::iterator >::reference >::type >::value, defaulted_constraint >::type = defaulted_constraint());
A mutable_buffer
value equivalent to:
mutable_buffer( data.size() ? &data[0] : 0, data.size() * sizeof(typename T::value_type));
