问如何在JNA中使用GetProcAddress？

已知C++代码

// dllmain.cpp : 定义 DLL 应用程序的入口点。

#include "pch.h"

#include <stdio.h>

#include <WTypes.h>

//定义CTXStringW为BSTR

typedef BSTR CTXStringW;

CTXStringW AllocTXString(const wchar_t* lpSrc)

{

if (lpSrc == NULL) return NULL;

BYTE* bBuffer = new BYTE[16 + (wcslen(lpSrc) + 1) * 2];

if (bBuffer == NULL) return NULL;

DWORD dwZero = 0;

DWORD dwCount = 3;

DWORD dwLenth = wcslen(lpSrc) + 1;

memmove(bBuffer + 0 * 4, &dwZero, 4);

memmove(bBuffer + 1 * 4, &dwCount, 4);

memmove(bBuffer + 2 * 4, &dwLenth, 4);

memmove(bBuffer + 3 * 4, &dwLenth, 4);

wcscpy((wchar_t*)(bBuffer + 4 * 4), lpSrc);

return CTXStringW(bBuffer + 16);

}

VOID GETQQ()

{

do {

HMODULE hKernelUtil = GetModuleHandle(L"KernelUtil.dll");

if (hKernelUtil == NULL)

{

OutputDebugStringA("Get KernelUtil Module failed \n");

break;

}

PVOID PtrGetSelfUin = GetProcAddress(hKernelUtil, "?GetSelfUin@Contact@Util@@YAKXZ");

if (PtrGetSelfUin == NULL)

{

OutputDebugStringA("Get GetSelfUin Function failed \n");

break;

}

DWORD uin = ((int(*)(int))PtrGetSelfUin)(1);

if (uin == NULL)

{

OutputDebugStringA("Invoke GetSelfUin Function failed \n");

break;

}

// Print QQ number

char szUin[MAX_PATH] = { 0 };

sprintf(szUin, "%d", uin);

} while (0);

}

BOOL APIENTRY DllMain( HMODULE hModule,

DWORD ul_reason_for_call,

LPVOID lpReserved

)

{

switch (ul_reason_for_call)

{

case DLL_PROCESS_ATTACH:

GETQQ();

break;

case DLL_THREAD_ATTACH:

case DLL_THREAD_DETACH:

case DLL_PROCESS_DETACH:

break;

}

return TRUE;

}

能不能拿Java代码实现获取当前登录的QQ号功能呢？
