22 * Error codes list

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