std::declare_reachable(3) C++ Standard Libary std::declare_reachable(3) NAME std::declare_reachable - std::declare_reachable Synopsis Defined in header <memory> void declare_reachable( void* p ); (since C++11) (removed in C++23) Declares the object referenced by the pointer p reachable. Reachable objects will not be deleted by the garbage collector or considered to be a leak by a leak detector even if all pointers to it are destroyed. An object may be declared reachable multiple times, in which case multiple calls to std::unde- clare_reachable would be needed to remove this property. For example, a XOR linked list needs to declare its nodes reachable if the implementation has garbage col- lection enabled. Parameters p - a safely-derived pointer or a null pointer Return value (none) Exceptions May throw std::bad_alloc if the system cannot allocate memory re- quired to track reachable objects. Example This section is incomplete Reason: no example See also undeclare_reachable declares that an object can be recycled (C++11)(removed in C++23) (function template) http://cppreference.com 2022.07.31 std::declare_reachable(3)
