buffer (38 of 42 overloads)

Create a new non-modifiable buffer from a contiguous container.

template<
    typename T>
const_buffer buffer(
    const T & data,
    std::size_t max_size_in_bytes,
    typename constraint< is_contiguous_iterator< typename T::const_iterator >::value, defaulted_constraint >::type  = defaulted_constraint());
Return Value

A const_buffer value equivalent to:

const_buffer(
    data.size() ? &data[0] : 0,
    min(
      data.size() * sizeof(typename T::value_type),
      max_size_in_bytes));
