  4. char array[length]; could just blow away your stack and leave you with nothing but wreckage.
  5. I'm a great fan of passing in the destination storage.
  6. To my knowledge, this construction is in C99, but not in C89.
  7. If you want a variable sized array then you need to dynamically allocate it (or, better yet; just use a vector).
