rbegin is supported.

After some search I found "reversible_ptr_container" in
#include 
I have my doubts if this is the one I should use because it is not easily found 
in the documentation and buried in the "details".
The questions are:
1. For rbegin() relative to ptr_vector - should I employ 
reversible_ptr_containier?
No.  ptr_vector uses reversible_ptr_container internally.
 If yes then short example will be highly 
appreciated.
2. How to get last element from ptr_vector (not using --end())?
Use back().

#include 

int main() {
    boost::ptr_vector<int> v;
    v.push_back(new int(0));
    boost::ptr_vector<int>::reverse_iterator iter = v.rbegin();
    int& ip = v.back();
}
