Accessing inactive union member - undefined? http://stackoverflow.com/questions/11373203/accessing-inactive-union-member-undefined is the set of bits that hold the value of type T. For trivially copyable types the value representation is a set of bits in..
Partial ordering with function template having undeduced context http://stackoverflow.com/questions/1180325/partial-ordering-with-function-template-having-undeduced-context it will find that T must be Q . Type deduction succeeds trivially for AT against T2 . BT against T1 Q T void typename Const T..
Aliasing `T*` with `char*` is allowed. Is it also allowed the other way around? http://stackoverflow.com/questions/12612488/aliasing-t-with-char-is-allowed-is-it-also-allowed-the-other-way-around magic_cast short c 42 If we assume that an int object is trivially constructed with the second line then that must mean c becomes.. char c 42 would be fine we would assume a short object is trivially constructed on the third line . Just like Alf I would also recommend..
Why can lambdas be better optimized by the compiler than plain functions? http://stackoverflow.com/questions/13722426/why-can-lambdas-be-better-optimized-by-the-compiler-than-plain-functions specifically for that object. The compiler can thus trivially inline the lambda call. For functions on the other hand the.. _some_lambda_type operator and can inline calls to it trivially. And invoking the function map with any other lambda would create..
When is overloading pass by reference (l-value and r-value) preferred to pass-by-value? http://stackoverflow.com/questions/18303287/when-is-overloading-pass-by-reference-l-value-and-r-value-preferred-to-pass-by the elements from rhs to lhs . When the element type is trivially copyable this may boil down to nothing but memcpy . This can..

If you have a member that can't be trivially copied you'll need to provide a copy constructor a destructor..
C++ format macro / inline ostringstream http://stackoverflow.com/questions/303562/c-format-macro-inline-ostringstream is contra indicated. Because it's a temporary we cannot trivially convert to an ostream object through casting. Both the constructor..
Const method that modifies *this without const_cast http://stackoverflow.com/questions/3484233/const-method-that-modifies-this-without-const-cast doing int j i removed const with const_cast... int k i ..trivially legal code j 5 k 5 And this is trivially legal. We now consider.. int k i ..trivially legal code j 5 k 5 And this is trivially legal. We now consider that i was this instead const int i 3..
How can I read and manipulate CSV file data in C++? http://stackoverflow.com/questions/415515/how-can-i-read-and-manipulate-csv-file-data-in-c rather than the current solution CSV files . You can trivially add adapters for other data formats such as bulk SQL import..
How many and which are the uses of “const” in C++? http://stackoverflow.com/questions/455518/how-many-and-which-are-the-uses-of-const-in-c const that make copy of that For making constants that trivially can't change double const PI 3.1415 For passing arbitrary objects..
How do I use arrays in C++? http://stackoverflow.com/questions/4810664/how-do-i-use-arrays-in-c detects an assignment from a pointer to a pointer which trivially succeeds. On the second line it detects an assignment from an..

How can I reliably get the address of an object? http://stackoverflow.com/questions/6494591/how-can-i-reliably-get-the-address-of-an-object and return no result. This reference to a function can be trivially converted into a pointer to function from @Konstantin According..
Is RVO (Return Value Optimization) applicable for all objects? http://stackoverflow.com/questions/7596183/is-rvo-return-value-optimization-applicable-for-all-objects of RVO where a temporary is returned that condition is trivially met the object is constructed in the return statement and well..
Why is template argument deduction disabled with std::forward? http://stackoverflow.com/questions/7779900/why-is-template-argument-deduction-disabled-with-stdforward lose nothing since any possible use of std forward t are trivially replaced by t . I think you'd understand things better if we..
