Since the following are both true:
int[] a = null;
int[] b = [];
assert(a is null);
assert(!a.length);
assert(b is null);
assert(!b.length);

D's I/O is dependent on C's FILE * API, so if you can make that write to
a string, then you could do it in D.
I don't think there's a way to do it in C. So likely

No, an allocation can trigger a collection. D does not
