如何得到网卡编号(MAC地址)？ [解决方法] 用下面的代码实现： int getMAC(char * mac) { NCB ncb; typedef struct _ASTAT_ { ADAPTER_STATUS adapt; NAME_BUFFER NameBuff [30]; } ASTAT, * PASTAT; ASTAT Adapter; typedef struct _LANA_ENUM { // le UCHAR length; UCHAR lana[MAX_LANA]; } LANA_ENUM ; LANA_ENUM lana_enum; UCHAR uRetCode; memset( &ncb, 0, sizeof(ncb) ); memset( &lana_enum, 0, sizeof(lana_enum)); ncb.ncb_command = NCBENUM; ncb.ncb_buffer = (unsigned char *) &lana_enum; ncb.ncb_length = sizeof(LANA_ENUM); uRetCode = Netbios( &ncb ); if( uRetCode != NRC_GOODRET ) return uRetCode ; for( int lana=0; lana{ ncb.ncb_command = NCBRESET; ncb.ncb_lana_num = lana_enum.lana[lana]; uRetCode = Netbios( &ncb ); if( uRetCode == NRC_GOODRET ) break ; } if( uRetCode != NRC_GOODRET ) return uRetCode; memset( &ncb, 0, sizeof(ncb) ); ncb.ncb_command = NCBASTAT; ncb.ncb_lana_num = lana_enum.lana[0]; strcpy( (char* )ncb.ncb_callname, "*" ); ncb.ncb_buffer = (unsigned char *) &Adapter; ncb.ncb_length = sizeof(Adapter); uRetCode = Netbios( &ncb ); if( uRetCode != NRC_GOODRET ) return uRetCode ; sprintf(mac,"%02X-%02X-%02X-%02X-%02X-%02X", Adapter.adapt.adapter_address[0], Adapter.adapt.adapter_address[1], Adapter.adapt.adapter_address[2], Adapter.adapt.adapter_address[3], Adapter.adapt.adapter_address[4], Adapter.adapt.adapter_address[5] ); return 0;
