Hi guys,
how can I allocate an (e.g. 16) byte aligned array?
In C I can do the following:
void *mem = malloc(1024+15);
void *ptr = ((uintptr_t)mem+15) & ~ (uintptr_t)0x0F;
memset_16aligned(ptr, 0, 1024);
free(mem);
I think in D it looks similar to this:
auto mem = new ubyte[1024+15];
auto ptr = (mem.ptr + 15) & ~ (...???...) 0x0F;
How to fill ...???... ?
Without a cast, the compiler tells me that I the types are incompatible
(ubyte* and int).
What's the correct syntax here?
PS: I don't want to use the experimental branch that provides
alignedAllocate().
void main() {
auto mem = new ubyte[1024+15];
auto ptr = cast(ubyte*)(cast(ulong)(mem.ptr + 15) & ~0x0FUL);
auto arr = ptr[0..1024];
}
