[Boost-users] polymorphic archive use and memory leak

Hi, I am using polymorphic archive in my code and I am using it as follows, 1 void func(std::stringstream &ss, boost::archive::polymorphic_oarchive *&ptr) 2 { 3 ptr = new boost::archive::polymorphic_text_oarchive(ss); 4 return; 5 } 6 int main() 7 { 8 std::stringstream ss; 9 boost::archive::polymorphic_oarchive *ptr = NULL; 10 func(ss, ptr); 11 delete ptr; //Will this delete object properly????? 12 } Now the question is, whether 'delete' one line no. 11 will work properly or not? And is this a right way to use polymorphic archive? Thanks, Sameer
