\begin{funcdesc}{buffer_info}{}
Return a tuple \code{(\var{address}, var{length})} giving the current
memory address and the length in bytes of the buffer used to hold
array's contents. This is occasionally useful when working with
low-level (and inherently unsafe) I/O interfaces that require memory
addresses, such as certain \code{ioctl} operations. The returned
numbers are valid as long as the array exists and no length-changing
operations are applied to it.

``Byteswap'' all items of the array. This is only supported for ``Byteswap'' all items of the array. This is only supported for
integer values. It is useful when reading data from a file written integer values. It is useful when reading data from a file written
