Zstandard library : usage examples
-
Simple compression : Compress a single file. Introduces usage of :
ZSTD_compress() -
Simple decompression : Decompress a single file. Only compatible with simple compression. Result remains in memory. Introduces usage of :
ZSTD_decompress() -
Multiple simple compression : Compress multiple files (in simple mode) in a single command line. Demonstrates memory preservation technique that minimizes malloc()/free() calls by re-using existing resources. Introduces usage of :
ZSTD_compressCCtx() -
Streaming memory usage : Provides amount of memory used by streaming context. Introduces usage of :
ZSTD_sizeof_CStream() -
Streaming compression : Compress a single file. Introduces usage of :
ZSTD_compressStream() -
Multiple Streaming compression : Compress multiple files (in streaming mode) in a single command line. Introduces memory usage preservation technique, reducing impact of malloc()/free() and memset() by re-using existing resources.
-
Streaming decompression : Decompress a single file compressed by zstd. Compatible with both simple and streaming compression. Result is sent to stdout. Introduces usage of :
ZSTD_decompressStream() -
Dictionary compression : Compress multiple files using the same dictionary. Introduces usage of :
ZSTD_createCDict()andZSTD_compress_usingCDict() -
Dictionary decompression : Decompress multiple files using the same dictionary. Result remains in memory. Introduces usage of :
ZSTD_createDDict()andZSTD_decompress_usingDDict()
