How to free memory to the system immediately?
What is your use case?
The use case is: we want deterministic memory management, (and
the application data is too big to fit into memory at once, so
have to be processed batch by batch).
suppose:
double[] data; // D type: dynamic array
As of 2021 what's the correct way to allocate and deallocate
(free memory to the system immediately) D's dynamic array?
If we use core.stdc.stdlib.malloc and free, e.g.
```
data = core.stdc.stdlib.malloc(n * double.sizeof);
// processing ...
free(data.ptr);
```
-- will data.length be set correctly (since it's a D type) with
malloc?
-- or we still need to manually set data.length = n? (in this
case, will it become GC managed, which we want to avoid in this
app)?
Thanks.
