buffer (21 of 38 overloads)

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

template<
    typename PodType,
    typename Allocator>
const_buffer buffer(
    const std::vector< PodType, Allocator > & data);

A const_buffer value equivalent to:

const_buffer(
   data.size() ? &data[0] : 0,
   data.size() * sizeof(PodType));

The buffer is invalidated by any vector operation that would also invalidate iterators.
