buffer (18 of 22 overloads)

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

    typename PodType,
    typename Allocator>
mutable_buffers_1 buffer(
    std::vector< PodType, Allocator > & data,
    std::size_t max_size_in_bytes);
Return Value

A mutable_buffers_1 value equivalent to:

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

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