class Example{ int str[BSize]; int *p; }; .... Or you might try the following (non-portable) idea
ar & BOOST_SERIALIZATION_NVP( make_binary_object(str, (p - str)* sizeof(int)) );
Thanks, that is closest to what I was after; I don't need a portable version here.
But really, I think you might be best off replacing the class above with
class Example { std::slist<int> str; // or maybe std::vector<int> str }
It was done using a fixed size buffer to avoid dynamic memory allocation (mainly for speed reasons). Serializing is relatively rare, but when it happens there will be a very large number of objects so I didn't want the full BSize elements stored. However as I worked through the class some more I found it can output a string representation, which uses fewer bytes. So in future I might add a parser for input and then switch to using that (though I'll be back to needing separate load/save functions then won't I, oh well :-). Darren
