How much is the overhead of smart pointers compared to normal pointers in C++?
...
std::unique_ptr has memory overhead only if you provide it with some non-trivial deleter.
std::shared_ptr always has memory overhead for reference counter, though it is very small.
std::unique_ptr has time overhead only during construc...

ACE vs Boost vs POCO [closed]
...POCO network library also provides support for higher level protocols like HTTP and SSL (possibly also in boost::asio, but I am not sure?).
Fair enough.
Integrated library has the advantage of having consistent coding, documentation and general "look and feel".

It seems to be a long dead project (but one I'm looking at continuing myself) but the add-in still works beautifully for me in VS2010 for both C++ and C#.
It has a few quirks (tab or...

RAII and smart pointers in C++
....
This is where smart pointers come in. The following example uses shared_ptr - I suggest you look at the different types of smart pointers to learn what you actually want to use.
shared_ptr<std::string> foo() {
shared_ptr<std::string> str = new std::string();
// Do cool things...
