To attach an external array (to avoid copies)
if external_sig == 0x0 returns to the inner allocated array and,
- with length == 0 returns to with the full length of the allocated inner array
- with length != 0, the given length if it does not exceed the allocate size ... otherwise the allocated size.
- Warning
- if used to bypass the streaming methods, the swapping is not garantee
