30 * Error codes list
31 *-*********************************************
32 * Error codes _values_ are pinned down since v1.3.1 only.
33 * Therefore, don't rely on values if you may link to any version < v1.3.1.
34 *
35 * Only values < 100 are considered stable.
36 *
37 * note 1 : this API shall be used with static linking only.
38 * dynamic linking is not yet officially supported.
39 * note 2 : Prefer relying on the enum than on its value whenever possible
40 * This is the only supported way to use the error list < v1.3.1
41 * note 3 : ZSTD_isError() is always correct, whatever the library version.
