operator - method

Pointer<Pointer<T>> operator -(
  1. int offset

A pointer to the offsetth Pointer<T> before this one.

Equivalent to this + (-offset).

Returns a pointer to the Pointer<T> whose address is offset times the size of Pointer<T> before the address of this pointer. That is, (this - offset).address == this.address - offset * sizeOf<Pointer<T>>().

Also, (this - offset).value is equivalent to this[-offset], and similarly for setting,


external Pointer<Pointer<T>> operator -(int offset);
