获取系统固件类型和Windows固件API学习

从Win7以上开始提供一个函数，可以获取系统固件类型；

BOOL GetFirmwareType(
  [in, out] PFIRMWARE_TYPE FirmwareType
);

FirmwareType是一个枚举，定义如下；

typedef enum _FIRMWARE_TYPE {
  FirmwareTypeUnknown,
  FirmwareTypeBios,
  FirmwareTypeUefi,
  FirmwareTypeMax
} FIRMWARE_TYPE, *PFIRMWARE_TYPE;

调用看一下；新建一个单文档工程；

void CFiretestView::OnDraw(CDC* pDC)
{
	CFiretestDoc* pDoc = GetDocument();
	ASSERT_VALID(pDoc);
	if (!pDoc)
		return;

	// TODO: 在此处为本机数据添加绘制代码
	FIRMWARE_TYPE myfire;
	GetFirmwareType(&myfire);
	switch (myfire)
	{
	case FirmwareTypeUnknown:
		pDC->TextOutW(50, 50, _T("不知名引导")); break;
	case FirmwareTypeBios:
		pDC->TextOutW(50, 50, _T("BIOS引导")); break;
	case FirmwareTypeUefi:
		pDC->TextOutW(50, 50, _T("UEFI引导")); break;
	case FirmwareTypeMax:
		pDC->TextOutW(50, 50, _T("Not implemented")); break;
