Gzip Compress In Memory and Base64 Encode

See more Gzip Examples

Demonstrates how to Gzip compress in-memory data and then encode the compressed data to base64. Unicode C++

    // See Global Unlock Sample for sample code.

    // This example will load a file into the fileData object.
    // Your application might load fileData from other sources..
