bsl::extent< T, N > Class Template Reference

If T is an array type, provides the member constant value equal to the number of elements along the Nth dimension of the array, if N is in [0, std::rank<T>::value). For any other type, or if T is an array of unknown bound along its first dimension and N is 0, value is 0. More...

Detailed Description

template<typename T, bsl::uintmax N = 0>
class bsl::extent< T, N >
