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

zip = Chilkat::CkZip.new()

success = zip.OpenZip("test.zip")
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

entry = Chilkat::CkZipEntry.new()

success = zip.EntryOf("hamlet.xml",entry)
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

entry.put_FileName("hamlet2.xml")

success = zip.EntryOf("helloWorld.pl",entry)
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

entry.put_FileName("hw.pl")

# Now unzip to the "test" subdirectory, under our current
# working directory:
numFilesUnzipped = zip.Unzip("test")
if (numFilesUnzipped < 0)
    print zip.lastErrorText() + "\n";
    exit
end

# The filenames within the .zip are unchanged, but it unzipped
# test/hw.pl and test/hamlet2.xm
