本文提供了三种使用C语言获取计算机MAC地址的方法。方法一通过NetBIOS API进行枚举和状态查询；方法二利用Windows Socket API及IP帮助程序API来获取适配器信息，包括名称、描述、MAC地址等；方法三则展示了如何使用IP帮助程序API获取IP地址表。

方法一：

void main()
{ 
	int  i;
	int  s32Num  = 0;
	NCB ncb; 
	LANA_ENUM lana_enum; 
	typedef struct _ASTAT_
	{
		ADAPTER_STATUS adapt;
		NAME_BUFFER    NameBuff [30];
	}ASTAT, * PASTAT;
	ASTAT Adapter; 


	unsigned char  *pu8Data;
	unsigned char 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 -1; 
	}

	for(i = 0; i < min(lana_enum.length, SDKID_MAX_NUM); i ++) 
	{ 
		memset( &ncb, 0, sizeof(ncb) ); 
		ncb.ncb_command = NCBRESET; 
		ncb.ncb_lana_num = lana_enum.lana[i]; 
		uRetCode = Netbios( &ncb ); 
		if( uRetCode != NRC_GOODRET )
		{
			continue; 
		}

		memset( &ncb, 0, sizeof(ncb) ); 
		ncb.ncb_command = NCBASTAT; 
		ncb.ncb_lana_num = lana_enum.lana[i]; 
		strcpy( (char* )ncb.ncb_callname, "*" ); 
		ncb.ncb_buffer = (unsigned char *) &Adapter; 
		ncb.ncb_length = sizeof(Adapter); 
		uRetCode = Netbios( &ncb ); 
		if( uRetCode != NRC_GOODRET ) 
		{
			continue; 
		}

		pu8Data  = Adapter.adapt.adapter_address;
		printf("mac: %02X-%02X-%02X-%02X-%02X-%02X", pu8Data[0], pu8Data[1], pu8Data[2], pu8Data[3], pu8Data[4], pu8Data[5]);
	} 
}

方法二：

#include <winsock2.h> 
#include <iphlpapi.h> 
#include <stdio.h> 
#pragma comment(lib,"Iphlpapi.lib") 

void main() 
{ 
	// 初始化winsock
	PIP_ADAPTER_INFO pAdapterInfo; 
	DWORD dwRetVal;
	ULONG ulOutBufLen = sizeof(IP_ADAPTER_INFO); 
	pAdapterInfo = (PIP_ADAPTER_INFO)malloc(ulOutBufLen); 
	dwRetVal = GetAdaptersInfo(pAdapterInfo, &ulOutBufLen);
	// 第一次调用GetAdapterInfo获取ulOutBufLen大小 
	if (dwRetVal == ERROR_BUFFER_OVERFLOW) 
	{ 
		free(pAdapterInfo); 
		pAdapterList  = NULL;
		pAdapterInfo  = (PIP_ADAPTER_INFO)malloc(ulOutBufLen); 
		dwRetVal = GetAdaptersInfo(pAdapterInfo, &ulOutBufLen);
	} 
	if (dwRetVal == NO_ERROR)
	{ 
		PIP_ADAPTER_INFO pAdapter = pAdapterInfo;
 
		while (pAdapter) 
		{ 
			printf("Adapter Name: \t%s\n", pAdapter->AdapterName); 
			printf("Adapter Desc: \t%s\n", pAdapter->Description); 
			printf("MAC Addr: \t%02x-%02x-%02x-%02x-%02x-%02x\n", 
				pAdapter->Address[0], 
				pAdapter->Address[1], 
				pAdapter->Address[2], 
				pAdapter->Address[3], 
				pAdapter->Address[4], 
				pAdapter->Address[5]); 
			printf("IP Address: \t%s\n", pAdapter->IpAddressList.IpAddress.String); 
			printf("IP Mask: \t%s\n", pAdapter->IpAddressList.IpMask.String); 
			printf("Gateway: \t%s\n", pAdapter->GatewayList.IpAddress.String); 
			pAdapter = pAdapter->Next; 
		}// end while 
	} 
	else 
	{ 
		printf("Call to GetAdaptersInfo failed.\n"); 
	}

	if (pAdapterInfo != NULL)
	{
		free(pAdapterInfo);
	}

	return 0;
} //end main

方法三：

#pragma comment(lib, "IPHLPAPI.lib") 
#include <winsock2.h> 
#include <iphlpapi.h> 
#include <stdio.h>
