...that is no larger than the amount of space allocated.  Strictly
speaking, if you only allocate 1 byte, the returned pointer need not
be suitably aligned for types that are larger than 1 byte (e.g. int
or double), since you can't store them there.  Some implementations
may take advantage of this to minimize the amount of wasted space,
but most do not.
