获取MAC地址
MAD地址是网卡的地址吧？ 在CMD里运行 ipconfig /all，应该是 NIC 部分的物理地址吧。
我下面运行怎么全是0呢
C/C++ code WSADATA wsaData; WORD sockVersion = MAKEWORD(2, 2); ::WSAStartup( sockVersion, &wsaData); PIP_ADAPTER_INFO padapterInfo = 0; ULONG ulong; GetAdaptersInfo(padapterInfo, &ulong); padapterInfo = (PIP_ADAPTER_INFO) malloc(ulong); int a = GetAdaptersInfo(padapterInfo, &ulong); u_char g_ucLocalMac[6]; memcpy(g_ucLocalMac, padapterInfo->Address, 6); printf("%02X - %02X - %02X - %02X - %02X - %02X ", g_ucLocalMac[0], g_ucLocalMac[1], g_ucLocalMac[2], g_ucLocalMac[3], g_ucLocalMac[4], g_ucLocalMac[5] );
