Using D1, I have a program that creates tons of float[] ; for performance
reasons, I would like them to be uninitialized.
I've tried replacing
float[] f = new float[x];
by
float[] f = cast(float[])std.gc.malloc(x*4);
Unfortunately I keep running into Access violation and sometimes Array
bounds

gc.malloc actually returns void[]
Bearophile's suggestion seems to work though, but it doesn't seem to improve

Hello everyone,
I would like to ask you about linking D shared objects (.dll and .so)
from a C++ program.
Say I have this C++ loader:
typedef int (*MagicFunction) ();
HMODULE handle = LoadLibraryA(DLibrary.dll);
if (handle)
{
MagicFunction fn = (MagicFunction) GetProcAddress(handle,

You can always make the variable uninitialized using
Check if GetProcAddress returns null? It seems to me you're looking
for _magicFunction but defining magicNumber, two different names.

Looks like void* to me...
Or is there another function I'm not aware of? I think it should be
GC.malloc, not

I don't think so, but you can do something like this with templates:

auto t = a;
a = b;
