I'm using a windows callback function where the user-defined

pass my D array then access it from that callback function. How
is the casting from LPARAM to my type array done in that case?
for example, I need something like this to work:
int[] arr = [1, 2, 3];
long l = cast(long) cast(void*) arr.ptr;
int[] a = cast(int[]) cast(void*) l;
LPARAM is not long on 32 bits, it's int. Use LPARAM instead of
long.
