* \note It is very important to note that even though this is a thread-safe
* replacement for inet_ntoa(), it is *not* reentrant. In a single
* thread, the result from a previous call to this function is no longer
* valid once it is called again. If the result from multiple calls to
* this function need to be kept or used at once, then the result must be
* copied to a local buffer before calling this function again.
