重载流操纵器操作符

Question

嗨，我试图重载运算符<<钩入

stream << std::endl;

以避免在不需要输出时追加'n'。我已经重载了:

std::ostream& operator<< (std::ostream& (*pf)(std::ostream&))
std::ostream& operator<< (std::ios& (*pf)(std::ios&))
std::ostream& operator<< (std::ios_base& (*pf)(std::ios_base&))

但是调用总是在basic_ostream

结束

_Myt& __CLR_OR_THIS_CALL operator<<(_Myt& (__cdecl *_Pfn)(_Myt&))
{// call basic_ostream manipulator
    _DEBUG_POINTER(_Pfn);
    return ((*_Pfn)(*this));
}

Answer 1

自己找到解决办法

问题是其他重载操作符返回std::ostream&
