C ++ DLL導出錯誤名稱

Question

我正在嘗試導出一個名為CreateGameClient的函數，當我執行dumpbin / exports時，我得到的是?CreateGameClient@@YAXXZ ，而我將DLL注入的程序則需要CreateGameClient而不是?CreateGameClient@@YAXXZ

我正在使用Visual Studio 2012，如果有幫助

這是我的代碼ExpFunc.h

#ifndef INDLL_H
#define INDLL_H

 #ifdef EXPORTING_DLL
  __declspec(dllexport) void CreateGameClient() ;
#else
  __declspec(dllimport) void CreateGameClient() ;
#endif

#endif

Main.cpp

#include "stdafx.h"
#include <Windows.h>
#include <string.h>
#include <sstream>
#include <stdio.h>
#include <fstream>
#define EXPORTING_DLL
#include "ExpFunc.h"

void WriteLogFile(const char*);
void CreateGameClient2(int);

char* logStr;
char* CGCNStr;
char buf[250];
DWORD pid = GetCurrentProcessId();

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{

    switch (ul_reason_for_call)
    {
        case DLL_PROCESS_ATTACH:
        case DLL_THREAD_ATTACH:
            logStr = "Attached To: %d";
            sprintf(buf, logStr, pid);
            WriteLogFile(buf);
            break;
        case DLL_THREAD_DETACH:
        case DLL_PROCESS_DETACH:
            logStr = "Detached To: %d";
            sprintf(buf, logStr, pid);
            WriteLogFile(buf);
            break;
    }
    return TRUE;
}

void CreateGameClient()
{
    CreateGameClient2(2);
}

void CreateGameClient2(int num)
{
    std::stringstream temp_str;
    temp_str << (num);
    std::string str = temp_str.str();
    const char* cstr2 = str.c_str();

    sprintf(buf, cstr2, pid);
    WriteLogFile(buf);
}

void WriteLogFile(const char* szString)
{
    FILE* pFile = fopen("logFile.txt", "a");
    fprintf(pFile, "%s\n",szString);
    fclose(pFile);

}

我嘗試了C ++ DLL導出：修飾過的名稱

但還是沒用

您必須使用extern "C" __declspec(...)裝飾函數的聲明和定義，否則，您將收到有關不一致的鏈接定義和不穩定行為的警告。
