std::remove_pointer(3) C++ Standard Libary std::remove_pointer(3) NAME std::remove_pointer - std::remove_pointer Synopsis Defined in header <type_traits> template< class T > (since C++11) struct remove_pointer; 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 behav- ior is undefined. Member types Name Definition type the type pointed to by T or T if it's not a pointer Helper types template< class T > (since C++14) using remove_pointer_t = typename remove_pointer<T>::type; 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; }; Example // Run this code #include <type_traits> static_assert ( std::is_same_v<int, int> == true && std::is_same_v<int, int*> == false && std::is_same_v<int, int**> == false && std::is_same_v<int, std::remove_pointer_t<int>> == true && std::is_same_v<int, std::remove_pointer_t<int*>> == true && std::is_same_v<int, std::remove_pointer_t<int**>> == false && std::is_same_v<int, std::remove_pointer_t<int* const>> == true && std::is_same_v<int, std::remove_pointer_t<int* volatile>> == true && std::is_same_v<int, std::remove_pointer_t<int* const volatile>> == true ); int main() {} See also is_pointer checks if a type is a pointer type (C++11) (class template) add_pointer adds a pointer to the given type (C++11) (class template) http://cppreference.com 2024.06.10 std::remove_pointer(3)
