39  * Error codes list
40  *-*********************************************
41  * Error codes _values_ are pinned down since v1.3.1 only.
42  * Therefore, don't rely on values if you may link to any version < v1.3.1.
43  *
44  * Only values < 100 are considered stable.
45  *
46  * 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.
