原标题:Is it safe to use std::bind with boost::signals2?

Is it safe to use std::bind to pass a member function to boost::signals2::signal::connect()? In other words, is boost::bind and std::bind interchangeable?

它与VC++ 2010 SP1一起汇编,但模板代码正在由我的头部接手,我恐怕我会通到不明确的行为领域。

例如,这相当安全:

boost::shared_ptr<ClassName> pValue = boost::make_shared<ClassName>(...);
signal.connect(boost::bind(&ClassName::FuncName, pValue, ...);

这相当安全,因为它储存了<条码>boost:共享_ptr作为其数据的一部分。

ClassName *pValue = new ClassName(...);
signal.connect(boost::bind(&ClassName::FuncName, pValue, ...);

This is conditionally safe. It instantly becomes unsafe if that connection still exists and you execute delete pValue.

我本人不相信“有条件安全”,而是 you。 重要的是,只要受其约束,你必须保留<条码>。

我在此议题上没有经验,但希望<条码>连接<>/条码>能接收任何实施有效职能电话操作者的信息。 应当安全地把它称作与签字相匹配的任何功能或功能物体,无论它是否起到推波助澜的作用: 造影图书馆是通用的,因此通常不收集其他执行细节。
