*-********************************************* |

* Error codes _values_ are pinned down since v1.3.1 only. |

* Therefore, don't rely on values if you may link to any version < v1.3.1. |
| 43 |
* |

* Only values < 100 are considered stable. |

* note 1 : this API shall be used with static linking only. |
| 47 |
* dynamic linking is not yet officially supported. |
| 48 |
* note 2 : Prefer relying on the enum than on its value whenever possible |
| 49 |
* This is the only supported way to use the error list < v1.3.1 |
| 50 |
* note 3 : ZSTD_isError() is always correct, whatever the library version. |
