handling return codes from CTYPES

Mike,

Thanks for your response - I was puzzled by one part of it though...

I (mis?)understood from the ctypes documentation that '>>> initResult = 
c_short(0)' would result in the creation of a ctypes 'short' called 
initResult and that this object would be mutable.  On that basis, I 
expected the following statement '>>> initResult = initScanLib( ... )' 
would assign the result of the call to initResult.

So, I can understand that I am not using the correct approach but I 
don't understand how I discarded the object I created.  Can you clarify 
please?
