Is there a simple (and quick) serialisation method for simple vectors?

[Pierre Couderc]

I want to serialise quickly a "simple" vector :
(simple is to say with basic types and no pointers)
such as :

class c
{
int i,j;
double z;
}

vector<c> cs;

Is there some simple efficient way such as :
memcpy(mybuff, cs , sizeof(what?))...

I am using SGI stl.

Thank you in advance

Supposedly you included the proper headers...

What's "mybuff"?

You should probably do

memcpy(mybuff, &cs[0], cs.size() * sizeof(c));
