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()
