1 | Zstandard library : usage examples |
2 | ================================== |
3 | |
4 | - [Simple compression](simple_compression.c) : |
5 | Compress a single file. |
6 | Introduces usage of : `ZSTD_compress()` |
7 | |
8 | - [Simple decompression](simple_decompression.c) : |
9 | Decompress a single file. |
10 | Only compatible with simple compression. |
11 | Result remains in memory. |
12 | Introduces usage of : `ZSTD_decompress()` |
13 | |
14 | - [Multiple simple compression](multiple_simple_compression.c) : |
15 | Compress multiple files (in simple mode) in a single command line. |
16 | Demonstrates memory preservation technique that |
17 | minimizes malloc()/free() calls by re-using existing resources. |
18 | Introduces usage of : `ZSTD_compressCCtx()` |
19 | |
20 | - [Streaming memory usage](streaming_memory_usage.c) : |
21 | Provides amount of memory used by streaming context. |
22 | Introduces usage of : `ZSTD_sizeof_CStream()` |
23 | |
24 | - [Streaming compression](streaming_compression.c) : |
25 | Compress a single file. |
26 | Introduces usage of : `ZSTD_compressStream()` |
27 | |
28 | - [Multiple Streaming compression](multiple_streaming_compression.c) : |
29 | Compress multiple files (in streaming mode) in a single command line. |
30 | Introduces memory usage preservation technique, |
31 | reducing impact of malloc()/free() and memset() by re-using existing resources. |
32 | |
33 | - [Streaming decompression](streaming_decompression.c) : |
34 | Decompress a single file compressed by zstd. |
35 | Compatible with both simple and streaming compression. |
36 | Result is sent to stdout. |
37 | Introduces usage of : `ZSTD_decompressStream()` |
38 | |
39 | - [Dictionary compression](dictionary_compression.c) : |
40 | Compress multiple files using the same dictionary. |
41 | Introduces usage of : `ZSTD_createCDict()` and `ZSTD_compress_usingCDict()` |
42 | |
43 | - [Dictionary decompression](dictionary_decompression.c) : |
44 | Decompress multiple files using the same dictionary. |
45 | Result remains in memory. |
46 | Introduces usage of : `ZSTD_createDDict()` and `ZSTD_decompress_usingDDict()` |
