I passed over the RPC method, and found a solution in a <ahref="http://members.tripod.com/~staskh/">page</a> maintained by StasKhirman and Raz Galili.... They describe a method of using the internalSNMP calls in Windows (NT, 95, and 2000 have worked for me) that areused by netstat and other windows utilities, but unfortunately provideno code example for finding the MAC code.</p><p class=inset>[Below is] a small program I've written up, so thathopefully other people won't have to go through the same learning curveI did with SNMP. I will also attach a file, snmpapi.cpp, that was writtenby Stas Khirman and distributed on his web page.</p><p class=inset>A great resource for those interestedin retrieving system info through this method is<a href="http://www.alvestrand.no/domen/objectid/top.html">http://www.alvestrand.no/domen/objectid/top.html</a>.</p></i><hr noshade size=1 color=#404040><h4 class=lmargin><a href="../examples/src/snmpmac.cpp">snmpmac.cpp</a></h4><pre><font color="0000ff"><strong>#include <font color="#008000"><snmp.h></font></strong></font><font color="0000ff"><strong>#include <font color="#008000"><conio.h></font></strong></font><font color="0000ff"><strong>#include <font color="#008000"><stdio.h></font></strong></font><strong>typedef</strong> <font color="#2040a0">BOOL</font><font color="4444FF">(</font><font color="#2040a0">WINAPI</font> <font color="4444FF">*</font> <font color="#2040a0">pSnmpExtensionInit</font><font color="4444FF">)</font> <font color="4444FF">(</font> <font color="#2040a0">IN</font> <font color="#2040a0">DWORD</font> <font color="#2040a0">dwTimeZeroReference</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">HANDLE</font> <font color="4444FF">*</font> <font color="#2040a0">hPollForTrapEvent</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">AsnObjectIdentifier</font> <font color="4444FF">*</font> <font color="#2040a0">supportedView</font><font color="4444FF">)</font><font color="4444FF">;</font><strong>typedef</strong> <font color="#2040a0">BOOL</font><font color="4444FF">(</font><font color="#2040a0">WINAPI</font> <font color="4444FF">*</font> <font color="#2040a0">pSnmpExtensionTrap</font><font color="4444FF">)</font> <font color="4444FF">(</font> <font color="#2040a0">OUT</font> <font color="#2040a0">AsnObjectIdentifier</font> <font color="4444FF">*</font> <font color="#2040a0">enterprise</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">AsnInteger</font> <font color="4444FF">*</font> <font color="#2040a0">genericTrap</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">AsnInteger</font> <font color="4444FF">*</font> <font color="#2040a0">specificTrap</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">AsnTimeticks</font> <font color="4444FF">*</font> <font color="#2040a0">timeStamp</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">RFC1157VarBindList</font> <font color="4444FF">*</font> <font color="#2040a0">variableBindings</font><font color="4444FF">)</font><font color="4444FF">;</font><strong>typedef</strong> <font color="#2040a0">BOOL</font><font color="4444FF">(</font><font color="#2040a0">WINAPI</font> <font color="4444FF">*</font> <font color="#2040a0">pSnmpExtensionQuery</font><font color="4444FF">)</font> <font color="4444FF">(</font> <font color="#2040a0">IN</font> <font color="#2040a0">BYTE</font> <font color="#2040a0">requestType</font>, <font color="#2040a0">IN</font> <font color="#2040a0">OUT</font> <font color="#2040a0">RFC1157VarBindList</font> <font color="4444FF">*</font> <font color="#2040a0">variableBindings</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">AsnInteger</font> <font color="4444FF">*</font> <font color="#2040a0">errorStatus</font>, <font color="#2040a0">OUT</font> <font color="#2040a0">AsnInteger</font> <font color="4444FF">*</font> <font color="#2040a0">errorIndex</font><font color="4444FF">)</font><font color="4444FF">;</font><strong>typedef</strong> <font color="#2040a0">BOOL</font><font color="4444FF">(</font><font color="#2040a0">WINAPI</font> <font color="4444FF">*</font> <font color="#2040a0">pSnmpExtensionInitEx</font><font color="4444FF">)</font> <font color="4444FF">(</font> <font color="#2040a0">OUT</font> <font color="#2040a0">AsnObjectIdentifier</font> <font color="4444FF">*</font> <font color="#2040a0">supportedView</font><font color="4444FF">)</font><font color="4444FF">;</font> <strong>void</strong> <font color="#2040a0">main</font><font color="4444FF">(</font><font color="4444FF">)</font><font color="4444FF"><strong>{</strong></font> <font color="#2040a0">HINSTANCE</font> <font color="#2040a0">m_hInst</font><font color="4444FF">;</font> <font color="#2040a0">pSnmpExtensionInit</font> <font color="#2040a0">m_Init</font><font color="4444FF">;</font> <font color="#2040a0">pSnmpExtensionInitEx</font> <font color="#2040a0">m_InitEx</font><font color="4444FF">;</font> <font color="#2040a0">pSnmpExtensionQuery</font> <font color="#2040a0">m_Query</font><font color="4444FF">;</font> <font color="#2040a0">pSnmpExtensionTrap</font> <font color="#2040a0">m_Trap</font><font color="4444FF">;</font> <font color="#2040a0">HANDLE</font> <font color="#2040a0">PollForTrapEvent</font><font color="4444FF">;</font>⌨️ 快捷键说明
