UDP sockets are connectionless, and are normally used with - the <a class="Xr">sendto(2)</a> and <a class="Xr">recvfrom(2)</a> calls, - though the <a class="Xr">connect(2)</a> call may also be used to fix the - destination for future packets (in which case the <a class="Xr">recv(2)</a> - or <a class="Xr">read(2)</a> and <a class="Xr">send(2)</a> or - <a class="Xr">write(2)</a> system calls may be used).</p> -<p class="Pp">UDP address formats are identical to those used by TCP. In - particular UDP provides a port identifier in addition to the normal Internet - address format. Note that the UDP port space is separate from the TCP port - space (i.e. a UDP port may not be “connected” to a TCP port). - In addition broadcast packets may be sent (assuming the underlying network - supports this) by using a reserved “broadcast address”; this - address is network interface dependent.</p> -<p class="Pp">There are two UDP-level - <a class="Xr">setsockopt(2)</a>/<a class="Xr">getsockopt(2)</a> options. - <code class="Dv">UDP_OPTIONS</code> may be used to change the default - behavior of the socket. For example:</p> -<div class="Bd Pp Li"> -<pre>setsockopt(s, IPPROTO_UDP, UDP_OPTIONS, NULL, 0);</pre> -</div> -<p class="Pp">The <code class="Dv">UDP_ENCAP</code> option can be used to - encapsulate ESP packets in UDP.
