Perhaps not using packed and adding the gcc option '-Wpadded' which will automagically catch the offenders for you might be more appropriate? Depending on manually checking can result in performance and correctness issues that are difficult to track. Mostly it's used for structs that are part of the public Xen interface. I don't want different compilers packing fields in different ways. -- Keir ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
