Re: [Boost-users] [smart_ptr] weak_ptr pointer semantics

No, it isn't.

if( shared_ptr<> p = weak.lock() ) {   p->thisWillNotAssert(); }

expired() should only be used for positive tests: if( weak.expired() ). Once a weak_ptr expires, it stays expired, so there is no potential for a race.

So that is a "no" on a get() thing? ;) Regards, Simon
