如何释放可以避免内存泄漏 Topic is solved

[kingkamg]

如下代码，主要用来将日志输出到两个不同的地方，请问如何是否才能保证内存不泄漏呢

Code: Select all

	m_pErrLog = new wxLogStderr;
	m_pErrLog->SetLogLevel(wxLOG_Info);
	wxLog::SetActiveTarget(m_pErrLog);
	wxLog::SetTimestamp(wxT("%m/%d/%Y %H:%M:%S")); 
	wxLog* pLog2 = new wxLogStream( new std::ofstream("BatchLog.txt") );
	m_pErrLog->SetLogLevel(wxLOG_Max);
	m_pLogchain = new wxLogChain(pLog2);
	m_pLogchain->PassMessages( true );

这是我释放的代码

Code: Select all

	wxLog::SetActiveTarget(NULL);	

	if ( m_pLogchain )
	{
		delete m_pLogchain;
		m_pLogchain = NULL;
	}

为什么不使用tr1::shared_ptr呢？

我不想用智能指针不行吗？只是想释放日志对象啊

[kingkamg]

Code: Select all

	wxLog::SetActiveTarget(NULL);

	if ( m_pLogchain )
	{
		delete m_pLogchain;
		m_pLogchain = NULL;
	}

	if ( m_pLogFile )
	{
		delete m_pLogFile;
		m_pLogFile = NULL;
	}

	if ( m_pOldLog )
		wxLog::SetActiveTarget( m_pOldLog );
