Remarks

The Subtraction method defines the subtraction operation for IntPtr objects. It enables code such as the following.

Languages that do not support custom operators can call the Subtract method instead.

The subtraction operation does not throw an exception if the result is too small to represent as a pointer on the specified platform. Instead, it is performed in an unchecked context.
