// DESCRIPTION         top
//        The bzero() function erases the data in the n bytes of the memory
//        starting at the location pointed to by s, by writing zeros (bytes
//        containing '\0') to that area.

//        The explicit_bzero() function performs the same task as bzero().
//        It differs from bzero() in that it guarantees that compiler
//        optimizations will not remove the erase operation if the compiler
//        deduces that the operation is "unnecessary".
// RETURN VALUE         top
//        None.
