获取本机IP和MAC地址

1、定义数据结构

typedef struct s_ip_fname
{
	//一个网卡可能有多个IP地址
	std::vector ips;
	std::string mac;
}s_ip_fname;

2、 函数

static int get_ipfname(std::vector &ff)
{
#define ADDR(x) pIpAdapterInfo->Address[x]
	PIP_ADAPTER_INFO pIpAdapterInfo = new IP_ADAPTER_INFO();
	unsigned long stSize = sizeof(IP_ADAPTER_INFO);
	int nRel = GetAdaptersInfo(pIpAdapterInfo, &stSize);
	DWORD netCardNum = 0;
	GetNumberOfInterfaces(&netCardNum);
	int IPnumPerNetCard = 0;
	if (ERROR_BUFFER_OVERFLOW == nRel)
	{
		delete pIpAdapterInfo;
		pIpAdapterInfo = (PIP_ADAPTER_INFO)new BYTE[stSize];
		nRel = GetAdaptersInfo(pIpAdapterInfo, &stSize);
		//return -1;
	}
	if (ERROR_SUCCESS == nRel)
	{
		//maybe we have >1 network card
		while (pIpAdapterInfo)
		{
			s_ip_fname ipf;
			switch (pIpAdapterInfo->Type)
			{
			case MIB_IF_TYPE_OTHER:
				//cout
