关于设备句柄的问题。

[Keng]

顺便帮忙解释一下代码谢谢。
l#pragma pack(push, 1)
struct DIOC_REGISTERS {
DWORD reg_EBX;
DWORD reg_EDX;
DWORD reg_ECX;
DWORD reg_EAX;
DWORD reg_EDI;
DWORD reg_ESI;
DWORD reg_Flags;
};
#pragma pack(pop)

sDiskImageInfo->hDevice = ::CreateFile("\\\\.\\vwin32", 0, 0, NULL, 0,
FILE_FLAG_DELETE_ON_CLOSE, NULL);
if( sDiskImageInfo->hDevice == INVALID_HANDLE_VALUE)
bRunNext = false;

// Reset Floppy Disk
reg.reg_EBX = 0;
reg.reg_EAX = 0x0000; // IOCTL for block devices
reg.reg_EDX = sDiskImageInfo->Driver;
reg.reg_EDI = 0; reg.reg_ESI= 0;
reg.reg_Flags = 0x0001; // assume error (carry flag is set)
dwResult = ::DeviceIoControl( sDiskImageInfo->hDevice,
VWIN32_DIOC_DOS_INT13,
®, sizeof(DIOC_REGISTERS), ®,
sizeof(DIOC_REGISTERS), &cb, 0);
请问sDiskImageInfo是一个控件吗？
上面的#号是什么意思？

请问如何声明物理设备句柄？顺便帮忙翻译一下上面的代码。
