This might be a really silly question but:
I've allocated some memory like this (Foo is a struct):
this._data = cast(Foo*) calloc(n, Foo.sizeof);
How can I then later check that there is a valid Foo at `this._data` or
`this._data + n`?
The correct way to do it is to make _data a slice:
Foo[] _data;
...
this._data = (cast(Foo*)calloc(n, Foo.sizeof)[0 .. n];
Note, you should also initialize the data, as calloc does not. This
might work:
_data[] = Foo.init;
