The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.
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 computer science, pointer swizzling is the conversion of references based on name or position into direct pointer references (memory addresses). It is typically performed during deserialization or loading of a relocatable object from a disk file, such as an executable file or pointer-based data structure .
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.
Kenneth Midworth Creer (1925 – 19 August 2020) was a British and Manx geophysicist who was the head of the geophysics department at the University of Edinburgh.He was the president of the European Geophysical Society from 1992 to 1994 and won the Gold Medal of the Royal Astronomical Society in 1996 among other accolades.
With Olympic flag football three years away, this much is becoming clear: the U.S. team should want a former LSU receiver on its roster. The four ex-Tigers competing in the Pro Bowl Games scored a ...
IBM later added tagged pointer support to the PowerPC architecture to support the IBM i operating system, which is an evolution of the System/38 platform. [3] A significant example of the use of tagged pointers is the Objective-C runtime on iOS 7 on ARM64, notably used on the iPhone 5S. In iOS 7, virtual addresses only contain 33 bits of ...
On C compilers targeting the 8086 processor family, far pointers were declared using a non-standard far qualifier; e.g., char far * p; defined a far pointer to a char. The difficulty of normalizing far pointers could be avoided with the non-standard huge qualifier. On other compilers it was done using an equally non-standard __far qualifier. [2]
