ec - error code to store error status to

Return value



The overload that does not take a std::error_code& parameter throws filesystem_error
on underlying OS API errors, constructed with the OS error code as the error code
argument. The overload taking a std::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. Any
overload not marked noexcept may throw std::bad_alloc if memory allocation fails.
