24  *  Error codes list
25  *-*********************************************
26  *  Error codes _values_ are pinned down since v1.3.1 only.
27  *  Therefore, don't rely on values if you may link to any version < v1.3.1.
28  *
29  *  Only values < 100 are considered stable.
30  *
31  *  note 1 : this API shall be used with static linking only.
32  *           dynamic linking is not yet officially supported.
33  *  note 2 : Prefer relying on the enum than on its value whenever possible
34  *           This is the only supported way to use the error list < v1.3.1
35  *  note 3 : ZSTD_isError() is always correct, whatever the library version.
