◆ HUF_decompress()

size_t HUF_decompress ( void * dst,
size_t dstSize,

HUF_decompress() : Decompress HUF data from buffer 'cSrc', of size 'cSrcSize', into already allocated buffer 'dst', of minimum size 'dstSize'. originalSize : must be the exact size of original (uncompressed) data. Note : in contrast with FSE, HUF_decompress can regenerate RLE (cSrcSize==1) and uncompressed (cSrcSize==dstSize) data, because it knows size to regenerate (originalSize).

Returns
: size of regenerated data (== originalSize), or an error code, which can be tested using HUF_isError()
