Pointer Safety and Garbage Collection (original) (raw)
| Functions | |
|---|---|
| void | std::declare_no_pointers (char *, size_t) |
| void | std::declare_reachable (void *) |
| pointer_safety | std::get_pointer_safety () noexcept |
| void | std::undeclare_no_pointers (char *, size_t) |
| template<typename _Tp > | |
| _Tp * | std::undeclare_reachable (_Tp *__p) |
Utilities to assist with garbage collection in an implementation that supports strict pointer safety. This implementation only supports relaxed pointer safety and so these functions have no effect.

◆ pointer_safety
Constants representing the different types of pointer safety.
Definition at line 136 of file memory.
◆ declare_no_pointers()
| void std::declare_no_pointers ( char * , size_t ) | inline |
|---|

Definition at line 149 of file memory.
◆ declare_reachable()
| void std::declare_reachable ( void * ) | inline |
|---|
Inform a garbage collector that an object is still in use.
