从一个dll中得到的函数，调用成功，无法返回
是调用intel的显卡驱动的某个函数出粗，代码如下：

C/C++ code

HMODULE hMoudle2=LoadLibraryEx("C:\\WINDOWS\\system32\\igxpgd32.dll",        NULL,DONT_RESOLVE_DLL_REFERENCES);         DWORD dwErrNum=0;    if   (hMoudle   ==   NULL)         dwErrNum=GetLastError(); //__stdcall wrong,FAR PASCAL wrong,__cdcel wrong//project page:stdcall(/gz) wrong,__cdecl (/Gd) wrong,fastcall :buffer overrun        typedef BOOL (*pDrvEnableDriver)(        ULONG iEngineVersion,        ULONG cj,        DRVENABLEDATA *pded        );    pDrvEnableDriver pMyDrvEnableDriver=(pDrvEnableDriver)GetProcAddress(hMoudle2,"DrvEnableDriver");    DRVENABLEDATA DrvData;    try    {        BOOL bRe=pMyDrvEnableDriver(DDI_DRIVER_VERSION_NT5,sizeof(DRVENABLEDATA),&DrvData); /* DrvData被赋值，bRe没有变化，函数无法返回，错误：Unhandled exception at 0x00024374 in graphedt.exe: 0xC0000005: Access violation reading location 0x00024374. */    dwErrNum=GetLastError();      //无法执行到这里        }catch(...)        {}

我晕了，改了各种调用方式都错。
反汇编部分如下：

Assembly code

HMODULE hMoudle2=LoadLibraryEx("C:\\WINDOWS\\system32\\igxpgd32.dll",        NULL,DONT_RESOLVE_DLL_REFERENCES);     100699FD  mov         esi,esp 100699FF  push        1    10069A01  push        0    10069A03  push        offset string "C:\\WINDOWS\\system32\\igxpgd32.dll"...

[解决办法]
Access violation reading location 0x00024374. ？
应该是GetProcAddress那里就出错了
[解决办法]
试试把DONT_RESOLVE_DLL_REFERENCES去掉，可能这个DLL必须执行DllMain的一些函数

[解决办法]
加 WINAPI 试试看，估计是调用方式不对出错了

typedef BOOL (WINAPI*pDrvEnableDriver)(
ULONG iEngineVersion,
ULONG cj,
DRVENABLEDATA *pded
);

[解决办法]
这个DLL里面会不会有什么问题呢？比如多线程什么的导致不能返回
