- I/O Library. This file has compiler specifics for Microsft C as there is no
- ANSI C standard for doing IO.
-
- MSC - uses intrinsic functions and the optimize will remove the function call
- overhead.
-
- We don't advocate putting compiler specifics in libraries or drivers but there
- is no other way to make this work.
