Why is volatile not considered useful in multithreaded C or C++ programming? http://stackoverflow.com/questions/2484980/why-is-volatile-not-considered-useful-in-multithreaded-c-or-c-programming a multithreaded context is that it doesn't provide all the guarantees we need. It does have a few properties we need but not all.. For thread safe accesses to shared data we need a guarantee that the read write actually happens that the compiler won't.. are reordered so the flag is set first volatile does guarantee the first point. It also guarantees that no reordering occurs..
What is the copy-and-swap idiom? http://stackoverflow.com/questions/3279543/what-is-the-copy-and-swap-idiom avoiding code duplication and providing a strong exception guarantee . How does it work Conceptually it works by using the copy constructor's.. it. The second is that it only provides a basic exception guarantee. If new int mSize fails this will have been modified. Namely.. size is wrong and the data is gone For a strong exception guarantee it would need to be something akin to dumb_array operator const..
When should static_cast, dynamic_cast and reinterpret_cast be used? http://stackoverflow.com/questions/332030/when-should-static-cast-dynamic-cast-and-reinterpret-cast-be-used later . A T something something_else is safe however and guaranteed to call the constructor. static_cast can also cast through.. int or all sorts of other nasty things. Largely the only guarantee you get with reinterpret_cast is that if you cast the result..
Finding C++ static initialization order problems http://stackoverflow.com/questions/335369/finding-c-static-initialization-order-problems application terminates. Multi Threaded Problem. C 11 does guarantee that this is thread safe. but C 03 does not officially guarantee.. that this is thread safe. but C 03 does not officially guarantee that the construction of static function objects is thread safe... gcc has an explicit patch as part of the compiler that guarantees that each static function object will only be initialized once..
RAII and smart pointers in C++ http://stackoverflow.com/questions/395123/raii-and-smart-pointers-in-c The reason this cannot be done in Java is that we have no guarantee over when the object will be destroyed so cannot guarantee when.. guarantee over when the object will be destroyed so cannot guarantee when a resource such as file will be freed.

What are Aggregates and PODs and how/why are they special? http://stackoverflow.com/questions/4178175/what-are-aggregates-and-pods-and-how-why-are-they-special is released or reused. For objects of POD types it is guaranteed by the standard that when you memcpy the contents of your object.. hold its original value. Do note that there is no such guarantee for objects of non POD types. Also you can safely copy POD objects.. POD int i char c goto label POD x label return 0 It is guaranteed that there will be no padding in the beginning of a POD object...
Is there a way to instantiate objects from a string holding their class name? http://stackoverflow.com/questions/582331/is-there-a-way-to-instantiate-objects-from-a-string-holding-their-class-name exist until program termination because we can't guarantee correct destruction order if map map new map_type return map..
