Create a new non-modifiable buffer that represents the given string.

template<
    typename Elem,
    typename Traits,
    typename Allocator>
const_buffer buffer(
    const std::basic_string< Elem, Traits, Allocator > & data,
    std::size_t max_size_in_bytes);

Return Value

A const_buffer value equivalent to:

const_buffer(
   data.data(),
   min(data.size() * sizeof(Elem), max_size_in_bytes));

Remarks

The buffer is invalidated by any non-const operation called on the given string object.
