SizeOf is always the good one, provided you are facing a statically declared array (whose length is known at compile time). On the other hand, if you face a pointer to some area, you have no way to guess the good value (and sizeof will always return the size of a pointer, ie 4 or 8 depending on your architecture). This is the whole point in using snprintf: it's a piece of information that the compiler cannot figure out automatically, so we force the programmer to think about it and pass the (hopefully) correct value to snprintf. CIL won't be of any help here.
