- * Convert a network address from binary to printable numeric format.
- * This API is copied from INRIA's IPv6 implementation, but it is a
- * bit bogus in two ways:
- *
- * 1) There is no value in passing both an address family and
- * an address length; either one should imply the other,
- * or we should be passing sockaddrs instead.
- * 2) There should by contrast be /added/ a length for the buffer
- * that we pass in, so that programmers are spared the need to
- * manually calculate (read: ``guess'') the maximum length.
- *
- * Flash: the API is also the same in the NRL implementation, and seems to
- * be some sort of standard, so we appear to be stuck with both the bad
- * naming and the poor choice of arguments.
