Does node::Buffer free foreign set memory on garbage collection?

[Bodo Kaiser]

Hello,

i want to know if a buffer which I have fed with own data is able to free this or if there is an api for manual freeing.

See:

Check src/node_buffer.h, there's a Buffer::New() method that takes a
free_callback argument.

By the way, your snippet has a bug, it's missing a return statement on
the scope.Close(...) line.

Thanks for the hint.

So the node Buffer does not free my assigned bytes when I do not use the free_callback?

Since you're using the version of Buffer::New() where it allocates memory for you, then yes, the memory will be free'd when the Buffer is garbage collected.

The non-free_callback versions of Buffer::New() copy the memory.
You're responsible for freeing the original memory.
