I'm trying to export a function called CreateGameClient
and when I do dumpbin /exports I get this instead ?CreateGameClient@@YAXXZ
and the program I'm injecting the DLL into needs CreateGameClient
and not ?CreateGameClient@@YAXXZ
And I'm using Visual Studio 2012 if that helps
This is my code 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);
}
I have tried C++ DLL Export: Decorated/Mangled names
but still didn't work
extern "C"
? – Iłya Bursov?CreateGameClient@@YAXXZ
actually givesvoid __cdecl CreateGameClient(void)
which is correct in your case. – Mahesh
