+ *  If number of bytes read is < number of bytes provided, then decompression operation is not complete. 
+ *  Remaining data will have to be presented again in a subsequent invocation. 
+ * 
+ *  The function result is an hint of the better srcSize to use for next call to LZ4F_decompress. 
+ *  Schematically, it's the size of the current (or remaining) compressed block + header of next block. 
+ *  Respecting the hint provides a small boost to performance, since it allows less buffer shuffling. 
+ *  Note that this is just a hint, and it's always possible to any srcSize value. 
+ *  When a frame is fully decoded, @return will be 0.
