Hi Peter, there's nothing magical in here, your understanding is correct.
I'll answer each question individually though.
> 1) I am wondering, why sizeof(ptr->Adaptername) is used instead of
That's just a style thing. I prefer sizeof(thing being copied) to
MAGIC_CONSTANT in case the structure being used changes. That's unlikely
in this case since the structure is defined in a public header. Since
it's a style thing there's no code-behavior reason to keep it this way.
> 2) Is 2a supposed to be saying 15
Yes, that's just a stupid bug apparently. Why I didn't use sizeof is
> 3) Why suddenly the change to use memcpy? and not some strcpy
> function as the code above it?
I wrote this on a different day :)
