Managed and Unmanaged Heap

Question

What is an unmanaged heap?

I thought that any CLR-managed object memory was heap-controlled, so why are we talking about unmanaged heap?

Answer 1

Imagine calling a Win32 function using P / Invoke and allocating some memory with malloc. The garbage collector does not have the visibility of this memory - it is unmanaged.

This may or may not be the context in which you, of course, have heard this term - if you can point out some examples to us, we can help you more.
