Zstandard library files
The lib directory contains several directories. Depending on target use case, it's enough to include only files from relevant directories.
API
Zstandard's stable API is exposed within zstd.h,
at the root of lib
directory.
Advanced API
Some additional API may be useful if you're looking into advanced features :
- common/error_public.h : transforms
size_t
function results into anenum
, for precise error handling. - ZSTD_STATIC_LINKING_ONLY : if you define this macro before including
zstd.h
, it will give access to advanced and experimental API. These APIs shall never be used with dynamic library ! They are not "stable", their definition may change in the future. Only static linking is allowed.
Modular build
Directory common/
is required in all circumstances.
You can select to support compression only, by just adding files from the compress/
directory,
In a similar way, you can build a decompressor-only library with the decompress/
directory.
Other optional functionalities provided are :
-
dictBuilder/
: source files to create dictionaries. The API can be consulted indictBuilder/zdict.h
. This module also depends oncommon/
andcompress/
. -
legacy/
: source code to decompress previous versions of zstd, starting fromv0.1
. This module also depends oncommon/
anddecompress/
. Library compilation must include directiveZSTD_LEGACY_SUPPORT = 1
. The main API can be consulted inlegacy/zstd_legacy.h
. Advanced API from each version can be found in their relevant header file. For example, advanced API for versionv0.4
is inlegacy/zstd_v04.h
.
Obsolete streaming API
Streaming is now provided within zstd.h
.
Older streaming API is still available within common/zbuff.h
.
It is now deprecated, and will be removed in a future version.
Consider migrating towards newer streaming API in zstd.h
.
Miscellaneous
The other files are not source code. There are :
- LICENSE : contains the BSD license text
- Makefile : script to compile or install zstd library (static and dynamic)
- libzstd.pc.in : for pkg-config (
make install
) - README.md : this file
