# [errno](https://github.com/rtmigo/errno)

Defines **system error code** constants for the OSs running the Dart platform.

With these numeric codes, the 

[OSError.errorCode](https://api.dart.dev/stable/dart-io/OSError/errorCode.html) 

property usually specifies the problem that occurred.

| OS             | Class           |

|----------------|-----------------|

| Android, Linux | `LinuxErrors`   |

| iOS, macOS     | `DarwinErrors`  |

| Windows        | `WindowsErrors` |

## Example 

``` dart

import 'dart:io';

import 'package:errno/errno.dart';

void main() {

  try {

    var lst = Directory("My Documents").listSync();

    print(lst);

  } on FileSystemException catch (exc) {

    if (exc.osError?.errorCode == WindowsErrors.pathNotFound) {

      

      print("The directory does not exist.");

    } else {

      rethrow;

    }

  }

}

```
