Casting to void tells the compiler you *know* you're not looking at the
result. As sprintf does generate one, the compiler can emit a warning when
the code fails to use it. This might help reduce the number of untested
error returns. Or increase the number of (void) casts, which doesn't seem
like a feature either.
