ZSTD_nextSrcSizeToDecompress() tells how much bytes to provide as input to ZSTD_decompressContinue().
|
|
This value is expected to be provided, precisely, as 'srcSize'.
|
|
Otherwise, compression will fail (result is an error code, which can be tested using ZSTD_isError() )
|
|
ZSTD_decompressContinue() 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.
