GZIP Decompression in memory

Currently I am saving a std::string to a file, and then using zlib to decompress that file using this code:

string gz_decompress(string compressedname){
      gzFile compressed = gzopen(compressedname.data(), "rb");
      if (!compressed) return "";
      char buffer[512];
      string decompressed;
      int num_read = 0;
      while ((num_read = gzread(compressed, buffer, sizeof(buffer))) > 0) {
            decompressed.append(buffer, num_read);
      }
      gzclose(compressed);
      return decompressed;
}

This is one of the slower parts of my program, and it seems like it would be more efficient to do the decompressing in memory.  I saw the example on codeproject, but was unable to get it to work.  If anyone could give me some code that will do this that would be great.

Thanks for any help
