 /* LZ4F_decompress()
  * Call this function repetitively to regenerate data compressed within srcBuffer.
- * The function will attempt to decode *srcSize from srcBuffer, into dstBuffer of maximum size *dstSize.
+ * The function will attempt to decode *srcSizePtr bytes from srcBuffer, into dstBuffer of maximum size *dstSizePtr.
  *
- * The number of bytes generated into dstBuffer will be provided within *dstSize (necessarily <= original value).
+ * The number of bytes generated into dstBuffer will be provided within *dstSizePtr (necessarily <= original value).
  *
- * The number of bytes effectively used from srcBuffer will be provided within *srcSize (necessarily <= original value).
+ * The number of bytes effectively used from srcBuffer will be provided within *srcSizePtr (necessarily <= original value).
  * If the number of bytes read is < number of bytes provided, then the decompression operation is not complete.
  * This typically happens when dstBuffer is not large enough to contain all decoded data.
- * LZ4F_decompress() will have to be called again, using the same src arguments (but eventually different dst arguments).
+ * LZ4F_decompress() will have to be called again, starting from where it stopped (srcBuffer + *srcSizePtr)
+ * The function will check this condition, and refuse to continue if it is not respected.
  * dstBuffer is supposed to be flushed between calls to the function, since its content will be rewritten.
+ * Different dst arguments can be used.
  *
  * The function result is an error code which can be tested using LZ4F_isError().
  * When a frame is fully decoded, the function result will be OK_FrameEnd(=1).
