vtoosld使用问题

用vtoolsd定义小端口驱动程序，
提示：clMS4D.lib(vdevice.obj) : error LNK2001: unresolved external symbol __DestroyDevice

我是这么定义的，
#define Declare_Virtual_Device_Ex(devName, RefData) extern \"C\" VDevice* \\
__cdecl _CreateDevice(); \\
extern \"C\" VOID __stdcall v86_api_entry();              \\
extern \"C\" VOID __stdcall pm_api_entry();      \\
extern \"C\" VOID __stdcall localControlDispatcher();      \\
extern \"C\" DDB The_DDB;      \\
extern \"C\" void (*VXD_SERVICE_TABLE[])();      \\
DDB The_DDB = {                  \\
0,      \\
DDK_VERSION,      \\
devName##_DeviceID,      \\
devName##_Major,      \\
devName##_Minor,      \\
0,      \\
{\' \',\' \',\' \',\' \',\' \',\' \',\' \',\' \'},      \\
devName##_Init_Order,      \\
(PGPUInt32)localControlDispatcher,      \\
(PGPUInt32)v86_api_entry,            \\
(PGPUInt32)pm_api_entry,      \\
0,0,RefData,      \\
(PGPUInt32)VXD_SERVICE_TABLE,      \\
0,            \\
0,            \\
__SIG__,            \\
};      \\
VDevice* __cdecl _CreateDevice()      \\
{      \\
return (VDevice*)new DEVICE_CLASS;      \\
}

// Declare_Port_Driver defines many important system-required fields for the
// driver.

#define Declare_Port_Driver(VName, _lgn, _asc, _rev, _fc, _ifr, _bt, _rd) \\
VOID __cdecl VName##_Aer(AEP*); \\
ILB VName##_Ilb; \\
DRP VName##_Drp={   \\
{\'X\',\'X\',\'X\',\'X\',\'X\',\'X\',\'X\',\'X\'}, \\
_lgn, \\
Driver->VName##_Aer, \\
&VName##_Ilb, \\
_asc, \\
_rev, \\
_fc,  \\
_ifr, \\
_bt,  \\
0,    \\
_rd}; \\
Declare_Virtual_Device_Ex(VName, (PGPUInt32)&VName##_Drp)

然后Declare_Port_Driver(PGPDISK, DRP_MISC_PD, PGPDISK_NAME, PGPDISK_REV,
PGPDISK_FEATURE, PGPDISK_IFR, DRP_BT_ESDI, 0)
怀疑是这里出了问题，大侠哪个用过？
