make_hierarchy

template<class _LUnit = void, class _L1, class ..._LevelDescs>
constexpr auto cuda::make_hierarchy(

_L1 __l1,

_LevelDescs... __ls

) noexcept

Creates a hierarchy from passed in levels.

This function takes any number of hierarchy_level_desc or derived objects and creates a hierarchy out of them. Levels need to be in ascending or descending order and the lowest level needs to be valid for thread_level unit.
