how to get firmware type of windows?

Question

I tried the below method, but it seems vague.

if (EnablePrivilege(SE_SYSTEM_ENVIRONMENT_PRIVILEGE) != ERROR_SUCCESS) 
{ 
return 0; //(unknown)

}

BYTE buffer[1];

DWORD result = GetFirmwareEnvironmentVariableW(SECURE_BOOT, EFI_GUID, buffer, sizeof(buffer));

if (result == 0) {

    DWORD error = GetLastError();

    if (error == ERROR_INVALID_FUNCTION || error == ERROR_ENVVAR_NOT_FOUND)  
     return FirmwareType_Legacy;

    return FirmwareType_Legacy;

}

return FirmwareType_UEFI;  
```is there any better approach?
