- * Description:
- * Send a local packet as a stream.

- * len Length of data to send
- * flags Send flags (ignored for now)
- *
- * Returned Value:
- * On success, returns the number of characters sent. On error,
- * -1 is returned, and errno is set appropriately (see send() for the
- * list of errno numbers).
