[QUOTE="John Harrison, post: 1508617"] There is no guaranteed way of determining how many bytes a vector is using. That should be pretty close, providing N == capacity() not N == size(). The capacity of a vector is how much storage it has allocated for itself, this is often more than the size of the vector. John [/QUOTE]
