OwnedCPtr

A C pointer returned by an @owned("free_fn") @c extern: Dream owns it, and the destructor calls free_fn(ptr) unless take() handed ownership back first.

public class OwnedCPtr

free_with

Releases ptr by calling the foreign function at address free.

public static extern fun free_with(free: usize, ptr: usize): void

get

The pointer, still owned (and later freed) by this object.

public fun get(): CPtr

take

Gives up ownership: the caller now frees the returned pointer, and this object holds NULL.

public fun take(): CPtr
