directory_iterator& operator++();
 (1) 
 (since C++17) 
directory_iterator& increment( std::error_code & ec );

 error code to store error status to
[edit] Return value
*this
[edit] Exceptions
Any overload not marked noexcept may throw std::bad_alloc  if memory allocation fails.
1) Throws std::filesystem::filesystem_error  on underlying OS API errors, constructed with the OS error code as the error code argument.
2) Sets a std::error_code & parameter to the OS API error code if an OS API call fails, and executes ec.clear () if no errors occur.
