- The routine lliinnkk__aaddddrr() interprets character strings representing link-
- level addresses, returning binary information suitable for use in system
- calls. The routine lliinnkk__nnttooaa() takes a link-level address and returns an
- ASCII string representing some of the information present, including the
- link level address itself, and the interface name or number, if present.
- This facility is experimental and is still subject to change.
-
- For lliinnkk__aaddddrr(), the string _a_d_d_r may contain an optional network inter-
- face identifier of the form ``name unit-number'', suitable for the first
- argument to ifconfig(4), followed in all cases by a colon and an inter-
- face address in the form of groups of hexadecimal digits separated by pe-
- riods. Each group represents a byte of address; address bytes are filled
- left to right from low order bytes through high order bytes.
-
- Thus le0:8.0.9.13.d.30 represents an ethernet address to be transmitted
- on the first Lance ethernet interface.

- lliinnkk__nnttooaa() always returns a null terminated string. lliinnkk__aaddddrr() has no
- return value. (See _B_U_G_S.)

- The lliinnkk__aaddddrr() and lliinnkk__nnttooaa() functions appeared in 4.3BSD-Reno.

- The returned values for link_ntoa reside in a static memory area.
-
- The function lliinnkk__aaddddrr() should diagnose improperly formed input, and
- there should be an unambiguous way to recognize this.
-
- If the _s_d_l___l_e_n field of the link socket address _s_d_l is 0, lliinnkk__nnttooaa()
- will not insert a colon before the interface address bytes. If this
- translated address is given to lliinnkk__aaddddrr() without inserting an initial
- colon, the latter will not interpret it correctly.
