func chilkatTest() {
    var success: Bool = false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let zip = CkoZip()!

    success = zip.open("qa_data/zips/test.zip")
    if success == false {
        print("\(zip.lastErrorText!)")
        return
    }

    // Iterate of each entry in the zip.
    // An entry can be a file or directory entry.  For each file, unzip to a byte array.
    var numEntries: Int = zip.numEntries.intValue
    print("NumEntries = \(numEntries)")

    let entry = CkoZipEntry()!
    var i: Int = 0
    while i < numEntries {
        zip.entry(at: i, entry: entry)
        if entry.isDirectory == false {
            var fileData: NSData = entry.inflate()
            // Do whatever you wish with the file data...
        }

        i = i + 1
    }

    zip.close()

    print("Finished.")
