This is most likely a simple question, but I cannot find an answer in the documentation. Classes that open a connection mostly have an IsConnected() method, but CkZip does not seem to have an IsOpen() or similar method.
Is there an alternative way of verifying that the CkZip has been initialized by either NewZip(), OpenZip() or OpenFromMemory()?
Related to above, I suppose CloseZip() can always be called, even when no file is open?
Is CloseZip() called internally once the CkZip object is destroyed?
