| ZSTD_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTD_decompressContinue(). |
| ZSTD_decompressContinue() will use previous data blocks to improve compression if they are located prior to current block. |
| Result is the number of bytes regenerated within 'dst'. |
| It can be zero, which is not an error; it just means ZSTD_decompressContinue() has decoded some header. |
