Is this os_memcmp use here referring to comparing memory presentations
of C structures in full? If so, I don't really think that is a good
approach as noted in the earlier comments in this thread. That is not
safe if the compiler does any padding between the fields and some of
those is not initialized and in any case, it would be much clearer to
provide an explicit function to do such comparison of the exact struct
members that need to be compared.
