int GZDecompress(Stream& out, Stream& in, int size, Gate2<int, int> progress)

Here the 'size' parameter is a number of bytes to be read from in.

The size of .gz is 75 bytes, but you put there 48.

GZDecompress(index_stream, in, in.GetSize());

Thanks! That helped. I was confused by the name �size�. IMO there was no need to provide size of the input stream because it can be easily retrieved from the input stream. The only useful size I could imagine in this situation was a minimal size of the output stream (to avoid multiple reallocations).

A few lines of documentation would help me a lot in this situation.

BTW, why MemStream? You can use 'out' as output directly without CopyStream.

This is just a testing application. In a real application I keep uncompressed data in memory.

Another alternative to MemStream would be StringStream, but it wouldn�t let me to reserve initial buffer (what seems to be a good idea), and I�d like to avoid multiple reallocations.

Thanks a lot for your help!
