remove_extent

template <class T>
struct remove_extent
{
   typedef see-below type;
};

type: If T is an array type, then removes the topmost array bound, otherwise leaves T unchanged.

C++ Standard Reference: 8.3.4.

Compiler Compatibility: If the compiler does not support partial specialization of class-templates then this template will compile, but the member type will always be the same as type T except where compiler workarounds have been applied.

Header: #include <boost/type_traits/remove_extent.hpp> or #include <boost/type_traits.hpp>
