The following concepts are relevant:
- Dynamic array: Maintained by the D runtime
Generally yes, but not always http://dpaste.dzfl.pl/ffbcb449
- Fixed-length array (aka static array): Can be on the stack
- Slice: An efficient tool to access a range of elements (of
any type of array)
Usually, it is the slice that gets passed:
void foo(int[] slice);
Isn't it a dynamic array? I don't understand listing slice as
separate type of arrays or mixing meaning of slice and dynamic
array. As far as D spec is concerned, slice is a SliceExpression
which produces dynamic array for array types.
A slice is made up of the pointer to the first element and the
number of elements:
struct __SomeImplementationDependentName__
{
size_t length;
void * ptr;
}
