[Question]Buffer's memory is allocated to a raw memory outside the v8 heap?

[yosuke-furukawa]

I found this sentence in our buffer.markdown.

A Buffer is similar to an array of integers but corresponds to a raw memory allocation outside the V8 heap.

In my understandings, Buffer is re-implemented using ArrayBuffer in io.js v3. I am thinking that ArrayBuffer allocates memory inside the v8 heap. So Buffer's memory also allocates to v8 heap inside.

If the documentation is wrong, I will send PR.

It's still explicitly allocated outside the heap.

Thank you. I have some misunderstandings.

[reqshark]

so.. do we have to free it? or does node::Buffer free its buffers?

[trevnorris]

@reqshark you only have to free the memory manually if you use node::Buffer::Copy(). Otherwise Buffer takes ownership of the memory. i.e. don't hang on to the same pointer you pass to node::Buffer::New().

thank you @trevnorris
