C++ 异常:抛出 std::string

I would like to throw an exception when my C++ methods encounter something weird and can't recover. Is it OK to throw a std::string pointer?

这是我期待做的事情:

void Foo::Bar() {
    if(!QueryPerformanceTimer(&m_baz)) {
        throw new std::string("it's the end of the world!");
    }
}

void Foo::Caller() {
    try {
        this->Bar(); // should throw
    }
    catch(std::string *caught) { // not quite sure the syntax is OK here...
        std::cout << "Got " << caught << std::endl;
    }
}

推荐答案

是的.std::exception 是C++ 标准库.您可能希望避免使用字符串作为异常类，因为它们本身在使用过程中会抛出异常.如果发生这种情况，那么你会在哪里?
