Decompress char array using GZIPDecompressorInputStream

Hi!

I have char array: tempDest;

If I use zlib without juce, i can write:

 gzipInflate((Bytef *)tempDest, &tempDestLen, (const Bytef*)compressedData, dataLength)

but when I use

juce::GZIPDecompressorInputStream

I can't decompress char array, how can i move char array into input stream?
