Detailed Description

template<class T, unsigned N = 0>
class std::extent< T, N >

obtains the size of an array type along a specified dimension

Template Parameters

T	type to query
N	specified array dimension

If T is an array type of rank greater than N, obtains the bound of the N 'th dimension of T as the value. If T is an array type of unknown bound, then the value is 0. In all other cases, value is 0.
