InflatingIOS

InflatingIOS(
    std::ostream & ostr,
    InflatingStreamBuf::StreamType type = InflatingStreamBuf::STREAM_ZLIB
);

Creates an InflatingIOS for expanding the compressed data passed through and forwarding it to the given output stream.

InflatingIOS

InflatingIOS(
    std::ostream & ostr,
    int windowBits
);
