<p>
Get a pointer to the internal array and assure that it is of at least the specified size. This is useful when the array contents are being set by some external or system function eg file read.
<p>
It is unsafe to assume that the pointer is valid for very long after return from this function. The array may be resized or otherwise changed and the pointer returned invalidated. It should be used for simple calls to atomic functions, or very careful examination of the program logic must be performed.
