std::filesystem::filesystem_error

文件系统：：文件系统[医]误差

Defined in header ​​
class filesystem_error;​(since C++17)

全班std::filesystem::filesystem_error定义一个异常对象，该异常对象在文件系统库中抛出函数的重载失败时抛出。

成员函数

(constructor)constructs the error object (public member function)
path1path2returns the paths that were involved in the operation that caused the error (public member function)
whatreturns the explanatory string (public member function)

继承自STD：系统[医]误差

成员函数

codereturns error code (public member function of std::system_error)
what virtualreturns explanatory string (virtual public member function of std::system_error)

继承自STD：：运行时[医]误差

继承自STD：例外

成员函数

(destructor) virtualdestructs the exception object (virtual public member function of std::exception)
what virtualreturns an explanatory string (virtual public member function of std::exception)
