A modern programming language that makes developers happier.

kotlinlang

I need to pass a `ByteArray` buffer from Kotlin to C so that it can be written to. The underlying lib expects it in the form of an `iovec`.

Do I _have_ to use `StableRef` to do this? `iovec.iov_base` is expecting the buffer in the form of a `COpaquePointer`.

Looks like maybe I want pinning? <https://kotlinlang.org/docs/native-c-interop.html#object-pinning>

You can look into `ByteArray.refTo()` , or pin and then `addressOf()`. The first is simpler but it will unpin after the C function returns, which might not be desirable.

What's the difference between using stableref and pinning? They seem really similar

Seems like stableref is maybe a two way street versus pinning being one way?

Yeah, they have different APIs and features as you noticed, but it's the same concept under the hood. I always thought they should be one thing
