Subject: Mac memory allocation: NewPtr or Ada's "new"

I'm learning to do Mac programming using GNAT under CodeBuilder,
and I'm a little confused about allocating memory from the heap.
Perhaps someone can help...
I have two Mac programming texts, and both of them tell me that
when I want to allocate memory from the heap, I should call the
NewPtr function, which seems to be functionally equivalent to the
Ada "new" allocator. I'd prefer to use the "new" allocator because
it's not tied to an OS, but I would like to understand any
subtle differences which aren't apparent on the surface.
Is there a operational difference between calling the MacOS NewPtr
and using Ada's "new" allocator? How is "new" implemented for
GNAT under MacOS?
Thanks!
