The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
std::is_pointer – std::is_pointer Synopsis Defined in header<type_traits> template <class T> (since C++ 11) struct is_pointer; Checks whether T is a pointer_to_object or a pointer to function (but not a pointer to member/member function). Provides the member constant value which is equal to true, if T is a object/function pointer type. Otherwise, value is equal to…
std::is_pod – std::is_pod Synopsis Defined in header <type_traits> template< class T > (since C++11) struct is_pod; (deprecated in C++20) If T is a PODType ("plain old data type"), that is, both trivial and standard-layout, provides the member constant value equal true. For any other type, value is false. The behavior is undefined if std::remove_all_extents_t<T> is…
std::is_placeholder – std::is_placeholder Synopsis Defined in header<functional> template <class T> (since C++ 11) struct is_placeholder; If T is the type of a standard placeholder (_1, _2, _3, …), then this template is derived from std::integral_constant<int,1>, std::integral_constant<int,2>, std::integral_constant<int,3>, respectively. If T is not a standard placeholder type, this template is derived from std::integral_constant<int,0> The template may…

std::is_object – std::is_object Synopsis Defined in header<type_traits> template <class T> (since C++ 11) struct is_object; If T is an object_type (that is any possibly cv-qualified type other than function, reference, or void types), provides the member constant value equal true. For any other type, value is false. Template parameters T – a type to check…
std::is_null_pointer – std::is_null_pointer Synopsis Defined in header<type_traits> template <class T> (since C++ 14) struct is_null_pointer; Checks whether T is the type std::nullptr_t. Provides the member constant value that is equal to true, if T is the type std::nullptr_t, const std::nullptr_t, volatile std::nullptr_t, or const volatile std::nullptr_t. Otherwise, value is equal to false. Template parameters T…
