Au contraire; C was designed for that sort of work from the beginning,
since that was its first major application, and ANSI C did not break this.
One needs to be a bit careful nowadays about using things like "volatile",
since modern C compilers are much more aggressive than the DMR original
that was used to rewrite the Unix kernel in C, but that's a detail.

They are *almost* always better done in C.  Given a good compiler, it's
rare for something to be doable in assembler but not in C.
