	FlushType flush
)

Public Function Inflate ( _
	flush As FlushType _
) As Integer

public:
int Inflate(
	FlushType flush
)

Parameters

flush (FlushType): The flush to use when inflating.

Return Value

Z_OK if everything goes well.

Remarks

You must have set InputBuffer and OutputBuffer, NextIn and NextOut, and AvailableBytesIn and AvailableBytesOut before calling this method.

Examples

CopyC#

private void InflateBuffer()
{
    int bufferSize = 1024;
    byte[] buffer = new byte[bufferSize];
    ZlibCodec decompressor = new ZlibCodec();

    Console.WriteLine("\n============================================");
    Console.WriteLine("Size of Buffer to Inflate: {0} bytes.", CompressedBytes.Length);
    MemoryStream ms = new MemoryStream(DecompressedBytes);

    int rc = decompressor.InitializeInflate();

    decompressor.InputBuffer = CompressedBytes;
    decompressor.NextIn = 0;
    decompressor.AvailableBytesIn = CompressedBytes.Length;

    decompressor.OutputBuffer = buffer;

    // pass 1: inflate 
    do
    {
        decompressor.NextOut = 0;
        decompressor.AvailableBytesOut = buffer.Length;
        rc = decompressor.Inflate(FlushType.None);

        if (rc != ZlibConstants.Z_OK && rc != ZlibConstants.Z_STREAM_END)
            throw new Exception("inflating: " + decompressor.Message);

        ms.Write(decompressor.OutputBuffer, 0, buffer.Length - decompressor.AvailableBytesOut);
    }
    while (decompressor.AvailableBytesIn > 0 || decompressor.AvailableBytesOut == 0);

    // pass 2: finish and flush
    do
    {
        decompressor.NextOut = 0;
        decompressor.AvailableBytesOut = buffer.Length;
        rc = decompressor.Inflate(FlushType.Finish);

        if (rc != ZlibConstants.Z_STREAM_END && rc != ZlibConstants.Z_OK)
            throw new Exception("inflating: " + decompressor.Message);

        if (buffer.Length - decompressor.AvailableBytesOut > 0)
            ms.Write(buffer, 0, buffer.Length - decompressor.AvailableBytesOut);
    }
    while (decompressor.AvailableBytesIn > 0 || decompressor.AvailableBytesOut == 0);

    decompressor.EndInflate();
}
