Certain blocks in nTop have what is called an Overload, which means they have multiple input configurations and may have the option to return different Output types. Not every block function has an overload, but blocks that do have a chevron icon next to their name. This icon indicates a drop-down menu that contains the block’s overloads.For example, with the Add block, a user can select the following overloads for both inputs “Operand A” and “Operand B”. Below are the overloads for the Add block.
