DHCP is an extension of BOOTP. Like BOOTP, it allows a target to configure itself dynamically by using the network to get its IP address, a boot file name, and the DHCP server's address. The relay agent forwards DHCP messages between clients and servers resident on different subnets. The standard DHCP server, if present on a subnet, can also forward messages across subnet boundaries. The relay agent is needed only if there is no DHCP server running on the subnet. The <b><i>dhcprLibInit</i>( )</b>routine links this library into the VxWorks system. This happens automaticallyif <b>INCLUDE_DHCPR</b> is defined at the time the system is built, as long as <b>INCLUDE_DHCPS</b> is <i>not</i> also defined.<p></blockquote><h4>HIGH-LEVEL INTERFACE</h4><blockquote><p>The <b><i>dhcprInit</i>( )</b> routine initializes the relay agent automatically. The relay agent forwards incoming DHCP messages to the IP addresses specified at build time in the <b>dhcpTargetTbl[]</b> array in <b>usrNetwork.c</b>. <p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><b>dhcprLib.h</b><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./dhcprLib.html#top">dhcprLib</a></b>, RFC 1541, RFC 1533</body></html>⌨️ 快捷键说明
