Isn't Wiring just a C function. At least that is what I see when I look at the Arduino core source files.
"Wiring" is the name of the language/environment that is implemented for Arduino development.
In practice, it is just C with a dash of C++, some training wheels, and some bits and bobs whose purpose seems mainly to confuse folks who are used to C or C++, so I can understand your confusion.
