In computer science, a smart pointer is an abstract data type that simulates a pointer while providing added features, such as automatic memory management or bounds checking. Such features are intended to reduce bugs caused by the misuse of pointers, while retaining efficiency.
An autorelative pointer is a pointer whose value is interpreted as an offset from the address of the pointer itself; thus, if a data structure has an autorelative pointer member that points to some portion of the data structure itself, then the data structure may be relocated in memory without having to update the value of the auto relative ...
In the C++ programming language, auto_ptr is an obsolete smart pointer class template that was available in previous versions of the C++ standard library (declared in the <memory> header file), which provides some basic RAII features for C++ raw pointers. It has been replaced by the unique_ptr class.
Tools such as Polyspace, TotalView, Valgrind, Mudflap, [8] AddressSanitizer, or tools based on LLVM [9] can also be used to detect uses of dangling pointers. Other tools (SoftBound, Insure++, and CheckPointer) instrument the source code to collect and track legitimate values for pointers ("metadata") and check each pointer access against the ...
Tombstones are a mechanism to detect dangling pointers and mitigate the problems they can cause in computer programs. Dangling pointers can appear in certain computer programming languages, e.g. C, C++ and assembly languages. A tombstone is a structure that acts as an intermediary between a pointer and its target, often heap-dynamic data in memory.
In MC++, there were two different types of pointers: __nogc pointers were normal C++ pointers, while __gc pointers worked on .NET reference types. In C++/CLI, however, the only type of pointer is the normal C++ pointer, while the .NET reference types are accessed through a "handle", with the new syntax ClassName ^ (instead of ClassName *). This ...
A function pointer, also called a subroutine pointer or procedure pointer, is a pointer referencing executable code, rather than data. Dereferencing the function pointer yields the referenced function , which can be invoked and passed arguments just as in a normal function call.
In computer science, a tagged pointer is a pointer (concretely a memory address) with additional data associated with it, such as an indirection bit or reference count.This additional data is often "folded" into the pointer, meaning stored inline in the data representing the address, taking advantage of certain properties of memory addressing.
