异常
The overload that does not take an error_code & parameter throws filesystem_error on underlying OS API errors, constructed with from as the first argument, to as the second argument, and the OS error code as the error code argument. std:: bad_alloc may be thrown if memory allocation fails. The overload taking an error_code & parameter sets it to the OS API error code if an OS API call fails, and executes ec. clear ( ) if no errors occur. This overload has
