Detailed Description

Exception for signalling an I/O error. If the problem originates from the (external) stream-object, then the original exception is enclosed here as a nested exception. In order to access the nested exception, use something like this:

try
    {
        spReader->Open(stream);
    }
    catch (LibCZIIOException& excp)
    {
        try
        {
            excp.rethrow_nested();
        }
        catch (std::ios_base::failure& innerExcp) // assuming that is the exception you 
        {                                         // expect to be thrown from the stream-object
         ....
        }
    }
