帮我看看下面代码，编译不过。

#include <basedef.h>
#include <vmm.h>
#include <vxdwraps.h>
#include <configmg.h>
#include <debug.h>
#include <vwin32.h>
#include <winerror.h>
...
BOOL g_bDevelop = FALSE; // development state
...
void _stdcall KBSetEvent(DIOCPARAMETERS *_lpDIOCParams)
{
DWORD dwEvent;
OVERLAPPED *polp;

polp = (OVERLAPPED *)(_lpDIOCParams->lpoOverlapped);
dwEvent = _VWIN32_OpenVxDHandle(polp->O_hEvent, OPENVXD_TYPE_EVENT);

_VWIN32_SetWin32Event(dwEvent);
_VWIN32_CloseVxDHandle(dwEvent);
}

DWORD _stdcall DIOC_Set_Development_State(DWORD dwDDB, DWORD hDevice, DIOCPARAMETERS *lpDIOCParms)
{
if (NULL == lpDIOCParms)
{
KBSetEvent(lpDIOCParms);
return 0;
}
if (lpDIOCParms->cbInBuffer >= 4)
{
if (NULL != lpDIOCParms->lpvInBuffer)
{
g_bDevelop = *((DWORD *)(lpDIOCParms->lpvInBuffer));
Debug_Printf("g_bDevelop:%d", g_bDevelop);
}
}
KBSetEvent(lpDIOCParms);
return 0;
}

error code:
external symbol __VWIN32_CloseVxDHandle/__VWIN32_SetWin32Event/__VWIN32_OpenVxDHandle
另：
与win32同步处理能这样处理吗？
