  2. Pointer (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Pointer_(computer_programming)

    In C++ pointers to non-static members of a class can be defined. If a class C has a member T a then &C::a is a pointer to the member a of type T C::*. This member can be an object or a function. [16] They can be used on the right-hand side of operators .* and ->* to access the corresponding member.

  3. Function pointer - Wikipedia

    en.wikipedia.org/wiki/Function_pointer

    Function pointers allow different code to be executed at runtime. They can also be passed to a function to enable callbacks. Function pointers are supported by third-generation programming languages (such as PL/I, COBOL, Fortran, [1] dBASE dBL [clarification needed], and C) and object-oriented programming languages (such as C++, C#, and D). [2]

  4. Tombstone (programming) - Wikipedia

    en.wikipedia.org/wiki/Tombstone_(programming)

    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.

  5. Reference counting - Wikipedia

    en.wikipedia.org/wiki/Reference_counting

    Objects that are shared but not owned can be accessed via a reference, raw pointer, or iterator (a conceptual generalisation of pointers). However, by the same token, C++ provides native ways for users to opt-into such functionality: C++11 provides reference counted smart pointers, via the std::shared_ptr class, enabling automatic shared memory ...

  6. Pointer analysis - Wikipedia

    en.wikipedia.org/wiki/Pointer_analysis

    In computer science, pointer analysis, or points-to analysis, is a static code analysis technique that establishes which pointers, or heap references, can point to which variables, or storage locations.

  7. The Power of 10: Rules for Developing Safety-Critical Code

    en.wikipedia.org/wiki/The_Power_of_10:_Rules_for...

    The ten rules are: [1] Avoid complex flow constructs, such as goto and recursion. All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation after initialization. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible.

  8. Hazard pointer - Wikipedia

    en.wikipedia.org/wiki/Hazard_pointer

    Hazard pointers can be used to address both of these problems. In a hazard-pointer system, each thread keeps a list of hazard pointers indicating which nodes the thread is currently accessing. (In many systems this "list" may be probably limited to only one [1] [2] or two elements.) Nodes on the hazard pointer list must not be modified or ...

  9. Smart pointer - Wikipedia

    en.wikipedia.org/wiki/Smart_pointer

    Smart pointers typically keep track of the memory they point to, and may also be used to manage other resources, such as network connections and file handles. Smart pointers were first popularized in the programming language C++ during the first half of the 1990s as rebuttal to criticisms of C++'s lack of automatic garbage collection. [1] [2]
