How to get std::deque pointer to the raw data?

Question

I know for std::vector, std::vector: data() and &something[0] are both OK, what about std::deque? There is no data() function for std::deque.

Edit: if std::deque is not guaranteed to use contiguous storage, how do i implement a deque that can get the raw data ?

Answer 1

The data contained in deque is not guaranteed to be placed in continuous memory block. This means that there could not be function similar to data() of vector.

Answer 2

No, the double-ended queue is a dynamically growing data structure. Unlike the std::vector it is not layed-out in memory like an array but as arbitrary memory locations pointing to the previous and to the next memory section.
