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](zstd.h),
|
|
|
|
|
at the root of `lib` directory.

#### Advanced API
|

|
|
|
|
2016-07-17 18:42:21 +00:00
|
|
|
Some additional API may be useful if you're looking into advanced features :
|
2016-07-18 01:52:47 +00:00
|
|
|
- common/error_public.h : transforms `size_t` function results into an `enum`,
|
2016-07-17 18:42:21 +00:00
|
|
|
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 :
|
2016-02-17 16:47:29 +00:00
|
|
|
|
2016-07-18 01:52:47 +00:00
|
|
|
- `dictBuilder/` : source files to create dictionaries.
|
2016-07-17 18:42:21 +00:00
|
|
|
The API can be consulted in `dictBuilder/zdict.h`.
|
2016-07-18 01:52:47 +00:00
|
|
|
This module also depends on `common/` and `compress/` .
|
2016-02-17 16:47:29 +00:00
|
|
|
|
2016-07-18 01:52:47 +00:00
|
|
|
- `legacy/` : source code to decompress previous versions of zstd, starting from `v0.1`.
|
|
|
|
|
This module also depends on `common/` and `decompress/` .
|
2016-07-17 18:42:21 +00:00
|
|
|
Note that it's required to compile the library with `ZSTD_LEGACY_SUPPORT = 1` .
|
2016-07-18 01:52:47 +00:00
|
|
|
The main API can be consulted in `legacy/zstd_legacy.h`.
|
2016-07-17 18:42:21 +00:00
|
|
|
Advanced API from each version can be found in its relevant header file.
|
|
|
|
|
For example, advanced API for version `v0.4` is in `zstd_v04.h` .

|
|
|
|
2016-07-17 18:42:21 +00:00
|
|
|
Streaming is currently provided by `common/zbuff.h`.

|
- Makefile : script to compile or install zstd library (static and dynamic)
|
|
|
|
|
- libzstd.pc.in : for pkg-config (`make install`)
