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 normal way to do this is to have an int (or whatever, larger size means less likely to fall fowl on random data) that is initialised to a known "random" value. See the ELF magic headers for example.
