std::remove_pointer - cppreference.com (original) (raw)
| | | | | -------------------------------------------- | | ------------- | | template< class T > struct remove_pointer; | | (since C++11) |
Provides the member typedef type which is the type pointed to by T, or, if T is not a pointer, then type is the same as T.
If the program adds specializations for std::remove_pointer, the behavior is undefined.

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