Phinecos(洞庭散人) 专注于开源技术的研究与应用 Winpcap网络开发库入门 ??????Winpcap ????? ??????首先到/install/default.htm下载安装winpcap?驱动和DLL组件。  ??????然后到/devel.htm.下载winpcap开发包，解压到指定目录，这里我解压到C:\WpdPack_4_0_2\WpdPack，可以看到里面包含了：Lib,Include,文档和示例程序。  首先创建一个C++控制台程序，设置如下： 1）??“Configuration Properties - C/C++ - General”中，在Additional Include Directories加入Include路径(“C:\WpdPack_4_0_2\WpdPack\Include”)。 2）???“Configuration Properties - Linker - General”?中，在Additional Library Directories中加入?winpcap?库文件路径?( “C:\WpdPack_4_0_2\WpdPack\Lib” )?。 3）??“Configuration Properties - Linker - Input”中，?Additional Dependencies?加入用到的两个winpcap?库文件（wpcap.lib?and?Packet.lib?)?。 4）??Winpcap的远程访问，必须在预处理器中加入HAVE_REMOTE 示例程序1??获取适配器列表 #include?pcap.hint?_tmain(int?argc,?_TCHAR*?argv[]){????pcap_if_t?*?allAdapters;//适配器列表????pcap_if_t?*?adapter;????char?errorBuffer[?PCAP_ERRBUF_SIZE?];//错误信息缓冲区????if(?pcap_findalldevs_ex(?PCAP_SRC_IF_STRING,?NULL,?????????????????allAdapters,?errorBuffer?)?==?-1?)????{//检索机器连接的所有网络适配器????????fprintf(?stderr,?Error?in?pcap_findalldevs_ex?function:?%s\n,?errorBuffer?);????????return?-1;????}????if(?allAdapters?==?NULL?)????{//不存在人任何适配器????????printf(?\nNo?adapters?found!?Make?sure?WinPcap?is?installed.\n?);????????return?0;????}????int?crtAdapter?=?0;????for(?adapter?=?allAdapters;?adapter?!=?NULL;?adapter?=?adapter-next)????{//遍历输入适配器信息(名称和描述信息)????????printf(?\n%d.%s?,?++crtAdapter,?adapter-name?);????????printf(?--?%s\n,?adapter-description?);????}????printf(?\n?);????pcap_freealldevs(?allAdapters?);//释放适配器列表????system(?PAUSE?);????return?0;} 2?打开指定适配器并捕获数据包 #include?pcap.hint?_tmain(int?argc,?_TCHAR*?argv[]){????pcap_if_t?*?allAdapters;//适配器列表????pcap_if_t?*?adapter;????pcap_t???????????*?adapterHandle;//适配器句柄????struct?pcap_pkthdr?*?packetHeader;????const?u_char???????*?packetData;????char?errorBuffer[?PCAP_ERRBUF_SIZE?];//错误信息缓冲区????if(?pcap_findalldevs_ex(?PCAP_SRC_IF_STRING,?NULL,?????????????????allAdapters,?errorBuffer?)?==?-1?)
