While this is the common usage of C++, in fact it has enough low-level
capability to allow it to reference absolute addresses, which is enough
to make *anything* happen on address-mappped systems.

In fact, with _asm_ one can write the machine-dependent code needed to
manipulate processor state and therefore implement a low-level kernel,
which is what is needed to implement the basis of all those higher-level
I/O libraries.

Typically, C is used for this function, however, since it seems more
"honest" to do so.  ;-)
