### 7.8 Miscellaneous Extensions

— Function: sb-ext:array-storage-vector array

> Returns the underlying storage vector of `array`, which must be a non-displaced array.

> In `sbcl`, if `array` is a of type (SIMPLE-ARRAY `*` (*)), it is its own storage vector. Multidimensional arrays, arrays with fill pointers, and adjustable arrays have an underlying storage vector with the same `array-element-type` as `array`, which this function returns.

> Important note: the underlying vector is an implementation detail. Even though this function exposes it, changes in the implementation may cause this function to be removed without further warning.
