I don't really need to share the objects, but i do want to make sure no memory leakage occurs. Is it correct to use shared_ptr in this case?

I want to learn C++ by using Vim and MinGW as compiler. I'm interesting at "C++ Primer (4th Edition)" and "C++ Primer Plus (5th Edition)" but I don't know how about it different. It has no book store that I can review those books, so I want to know, what is the different between those book and which…

Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This…

Prototype : void read ( const std::string &imageSpec_ )
I call this function from managed c++ dll by passing a std::string.
When i debug the unmanaged c++ code the parameter imageSpec_ shows the value correctly…

After more than a few questions about deciding on C++ books I thought we could make a better community wiki version. Providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate…

Following the advice of this page, I'm trying to get shared_ptr to call IUnknown::Release() instead of delete:
IDirectDrawSurface* dds;
... //Allocate dds
return shared_ptr<IDirectDrawSurface>(dds, mem_fun_ref(&IUnknown::Release));
error C2784: 'std::const_mem_fun1_ref_t<_Result…

I'm having trouble getting intellisense to auto-complete shared pointers for boost 1.40.0. (It works fine for Boost 1.33.1.) Here's a simple sample project file where auto-complete does not work:
#include <boost/shared_ptr.hpp>
struct foo
{ bool func() { return true; }; };
void bar() {

I use std::tr1::shared_ptr extensively throughout my application. This includes passing objects in as function arguments. Consider the following:
class Dataset {...}
void f( shared_ptr< Dataset const > pds ) {...}
void g( shared_ptr< Dataset const > pds ) {...}
...
While passing a…

In the boost::shared_ptr destructor, this is done:
if(--*pn == 0)
{
boost::checked_delete(px);
delete pn;
}
where pn is a pointer to the reference counter, which is typedefed as
shared_ptr::count_type -> detail::atomic_count -> long
I would have expected the long to be volatile…
