Function Documentation

◆ main()

int main ( void )

Simple single-file test to compress rawData, decompress the result, then compare the decompressed version with the original.

◆ ZSTD_compress()

size_t ZSTD_compress	(	void *	dst,
		size_t	dstCapacity,
		const void *	src,
		size_t	srcSize,
		int	compressionLevel )

ZSTD_compress() : Compresses src content as a single zstd compressed frame into already allocated dst. Hint : compression runs faster if dstCapacity >= ZSTD_compressBound(srcSize).

Returns: : compressed size written into dst (<= `dstCapacity), or an error code if it fails (which can be tested using ZSTD_isError()).

◆ ZSTD_compressBound()

size_t ZSTD_compressBound ( size_t srcSize )

maximum compressed size in worst case single-pass scenario

◆ ZSTD_decompress()

size_t ZSTD_decompress	(	void *	dst,
		size_t	dstLen,
		const void *	src,
		size_t	srcLen )

Zstandard decompression functions. dst must point to a space at least as large as the reconstructed output.

For the case where the decompression library hasn't been included we add a dummy function to fake the process and stop the buffers being optimised out.

◆ ZSTD_isError()

unsigned ZSTD_isError ( size_t code )

tells if a size_t function result is an error code

ZSTD_isError() : tells if a return value is an error code symbol is required for external callers

◆ ZSTD_maxCLevel()

int ZSTD_maxCLevel ( void )

maximum compression level available
