* @return is always the same for a srcSize and prefsPtr.
* prefsPtr is optional : when NULL is provided, preferences will be set to cover worst case scenario.
* tech details :
- * @return includes the possibility that internal buffer might already be filled by up to (blockSize-1) bytes.

* It also includes frame footer (ending + checksum), since it might be generated by LZ4F_compressEnd().
