Contents

Member types

Name Definition
type the type pointed to by T or T if it's not a pointer

Helper types

template< class T >
using remove_pointer_t = typename remove_pointer<T>::type;
(since C++14)

Possible implementation

template< class T > struct remove_pointer                    {typedef T type;};
template< class T > struct remove_pointer<T*>                {typedef T type;};
template< class T > struct remove_pointer<T* const>          {typedef T type;};
template< class T > struct remove_pointer<T* volatile>       {typedef T type;};
template< class T > struct remove_pointer<T* const volatile> {typedef T type;};
