除了std::common_type和std::basic_common_reference(C++20 起)以外,<type_traits>中定义的模板均不可对由程序定义的类型特化。这包含各种类型特征和std::integral_constant类模板。 std::hash对由程序定义的类型的特化的必须满足散列(Hash)要求。 std::atomic的特化必须拥有弃置的复制构造函数,弃置的复制赋值运算符...

nmust be an integral assignment expression of value 1 or greater. This scheduling policy is also known asblock cyclic scheduling. Note: ifn=1, iterations of a loop are divided into chunks of size 1 and each chunk is assigned to a thread inround-robinfashion. This scheduling policy is also...
