This module depends on both `lib/common` and `lib/compress` . This module depends on both `lib/common` and `lib/compress` .
- `lib/legacy` : source code to decompress legacy zstd formats, starting from `v0.1.0`. - `lib/legacy` : source code to decompress legacy zstd formats, starting from `v0.1.0`.
This module depends on `lib/common` and `lib/decompress`. This module depends on `lib/common` and `lib/decompress`.
To enable this feature, it's required to define `ZSTD_LEGACY_SUPPORT` during compilation. To enable this feature, define `ZSTD_LEGACY_SUPPORT` during compilation.
Typically, with `gcc`, add argument `-DZSTD_LEGACY_SUPPORT=1`. Specifying a number limits versions supported to that version onward.
Using higher number limits versions supported.
For example, `ZSTD_LEGACY_SUPPORT=2` means : "support legacy formats >= v0.2.0". For example, `ZSTD_LEGACY_SUPPORT=2` means : "support legacy formats >= v0.2.0".
`ZSTD_LEGACY_SUPPORT=3` means : "support legacy formats >= v0.3.0", and so on. `ZSTD_LEGACY_SUPPORT=3` means : "support legacy formats >= v0.3.0", and so on.
Starting v0.8.0, all versions of `zstd` produce frames compliant with specification. Currently, the default library setting is `ZST_LEGACY_SUPPORT=5`.
As a consequence, `ZSTD_LEGACY_SUPPORT=8` (or more) doesn't trigger legacy support. It can be changed at build by any other value.
Also, `ZSTD_LEGACY_SUPPORT=0` means "do __not__ support legacy formats". Note that any number >= 8 translates into "do __not__ support legacy formats",
since all versions of `zstd` >= v0.8 are compatible with v1+ specification.
`ZSTD_LEGACY_SUPPORT=0` also means "do __not__ support legacy formats".
Once enabled, this capability is transparently triggered within decompression functions. Once enabled, this capability is transparently triggered within decompression functions.
It's also possible to invoke directly legacy API, as exposed in `lib/legacy/zstd_legacy.h`. It's also possible to invoke directly legacy API, as exposed in `lib/legacy/zstd_legacy.h`.
Each version also provides an additional dedicated set of advanced API. Each version also provides an additional dedicated set of advanced API.
For example, advanced API for version `v0.4` is exposed in `lib/legacy/zstd_v04.h` . For example, advanced API for version `v0.4` is exposed in `lib/legacy/zstd_v04.h` .
Note : `lib/legacy` only supports _decoding_ legacy formats. Note : `lib/legacy` only supports _decoding_ legacy formats.
- Similarly, you can define `ZSTD_LIB_COMPRESSION, ZSTD_LIB_DECOMPRESSION`, `ZSTD_LIB_DICTBUILDER`, - Similarly, you can define `ZSTD_LIB_COMPRESSION, ZSTD_LIB_DECOMPRESSION`, `ZSTD_LIB_DICTBUILDER`,
and `ZSTD_LIB_DEPRECATED` as 0 to forgo compilation of the corresponding features. This will and `ZSTD_LIB_DEPRECATED` as 0 to forgo compilation of the corresponding features. This will
