That should work.
Thanks.
Will that reuse the existing allocate memory at `thePtr` for
internal storage of the D array? If so how is the GC aware of
this memory?
Is there any tutorials, reference documentation, etc on these
matters?
To my knowledge it should reuse the memory and not inform the GC
about it. It basically makes D treat that pointer like a slice.
If you need to confirm that it is doing that, just @nogc it. If
it allocates it'll fail.
I'm not aware of much docs regarding these sort of tricks. But I
believe it was Adam who originally discovered this little trick.
Atleast I'm pretty sure he is how I learnt about it. On D.learn
as well.
