Hi, I have this code:

#include

class A{ // base class public: };

class B : public A{ public: int b1; };

typedef boost::shared_ptr<A> tSmartA; typedef boost::shared_ptr<B> tSmartB;

void foo (tSmartB& smartOne) // should get a pointer to derived { }

int main () { tSmartA a(new B); foo(a); // This line doesn't compile because foo expects to get tSmartB return 0; }

How can I then send a to foo() ?

Thanks

Yossi
