array_get - get pointer to nth element in array

#include <array.h>

void* array_get(array* x, uint64 membersize, int64 pos);

array x; int64 pos; t* p = array_get(&x,sizeof(t),pos);

array_get is similar to array_allocate, but it does not allocate any extra bytes, and it does not initialize any extra bytes. It returns 0 if x is unallocated, for example, or if fewer than (pos+1)*sizeof(t) bytes are initialized.
