Q: How can I programmatically retrieve my device's MAC address?
You can retrieve the on-board adapter's MAC address using the GetAdaptersInfo() API something like this:
PIP_ADAPTER_INFO pAdapterInfo = NULL;
ULONG OutBufLen = 0;
ULONG ret = 0;
// first get size of AdapterInfo
OutBufLen = 0;
ret = GetAdaptersInfo(pAdapterInfo, &OutBufLen);
if (ret == ERROR_BUFFER_OVERFLOW)
{
// Allocate memory to get AdatperInfo
pAdapterInfo = (PIP_ADAPTER_INFO) malloc(OutBufLen);
ret = GetAdaptersInfo(pAdapterInfo, &OutBufLen);
if (ret == ERROR_SUCCESS)
{
do
{
RETAILMSG(TRUE, (_T(" Adapter Name = %a\r\n"), pAdapterInfo->AdapterName));
RETAILMSG(TRUE, (_T(" IP Address = %a\r\n"), pAdapterInfo->CurrentIpAddress->IpAddress.String));
RETAILMSG(TRUE, (_T(" Gateway = %a\r\n"), pAdapterInfo->GatewayList.IpAddress.String));
RETAILMSG(TRUE, (_T(" DHCP Server = %a\r\n"), pAdapterInfo->DhcpServer.IpAddress.String));
RETAILMSG(TRUE, (_T(" MAC Address = 0x%02x-0x%02x-0x%02x-0x%02x-0x%02x-0x%02x\r\n"),
pAdapterInfo->Address[0],
pAdapterInfo->Address[1],
pAdapterInfo->Address[2],
pAdapterInfo->Address[3],
pAdapterInfo->Address[4],
pAdapterInfo->Address[5]));
} while ((pAdapterInfo = pAdapterInfo->Next) != NULL);
}
free((PVOID)pAdapterInfo);
}
