CallDebuggerI understand this. What I'm saying is that the syntax suggest for Field.Type that the array portion belongs to the type and it's confusing. There is a big difference between and array of pointers and a pointer to an array.Josh wrote:The compiler recognizes this as no different than *POINT[3] because it is no different. A pointer is a pointer, no matter if a structure is assigned to it or not.

If you want a pointer to an array then you have to define a structure that contains an array.

Debug SizeOf(ARRAY_OF_POINTS_XY)I would say the term 'pointer to an array' is a matter of definition. In my opinion the pointer to the first element of an array could be seen as 'pointer to an array'.Demivec wrote:There is no such thing as a pointer to an array.
