Demonstrates how to use the CkGZip C++ class to compress and uncompress .gz file format files and memory.

void GZipExample(void)
    {
    // The CkGzip class is included with the "Chilkat Zip" license.
    CkGzip gzip;
    gzip.UnlockComponent("Anything for 30-day trial");

    // ungzip a .gz file:
    gzip.UncompressFile("helloWorld.txt.gz","helloWorld.txt");

    // Create a .gz compressed file.
    gzip.CompressFile("helloWorld.txt","helloWorld2.txt.gz");

    CkByteData byteData;

    // Ungzip from file to memory:
    gzip.UncompressFileToMem("helloWorld.txt.gz",byteData);

    // Access the data:
    const unsigned char *data = byteData.getData();
    int numBytes = byteData.getSize();

    // Compress from memory to file:
    gzip.CompressMemToFile(byteData,"helloWorld3.txt.gz");

    // Memory-to-memory compress:
    CkByteData compressedData;
    gzip.CompressMemory(byteData,compressedData);

    // Access the compressed data:
    data = compressedData.getData();
    numBytes = compressedData.getSize();

    // Memory-to-memory ungzip
    byteData.clear();
    gzip.UncompressMemory(compressedData,byteData);

    // Ungzip from memory to file:
    gzip.UncompressMemToFile(compressedData,"helloWorld4.txt");

    // Compress from file to memory:
    compressedData.clear();
    gzip.CompressFileToMem("helloWorld4.txt",compressedData);
