The Standard Template Library overloads its built-in swap function to exchange the contents of containers efficiently this way. [ 1 ] As pointer variables are usually of a fixed size (e.g., most desktop computers have pointers 64 bits long), and they are numeric, they can be swapped quickly using XOR swap .
Many C compilers support using compare-and-swap either with the C11 <stdatomic.h> functions, [8] or some non-standard C extension of that particular C compiler, [9] or by calling a function written directly in assembly language using the compare-and-swap instruction. The following C function shows the basic behavior of a compare-and-swap ...
Using the XOR swap algorithm to exchange nibbles between variables without the use of temporary storage. In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required.
In a 2001 paper, Harris gives a solution to concurrent maintenance of ordered linked list that is non-blocking, using a compare-and-swap (cas) primitive. [1] Insertion of n after p is simple: next ← p.next
Concurrent Building Blocks - C++ implementation of Hazard Pointer (called "SMR") and other lock-free data structures. Also has Java interfaces. Concurrency Kit Archived 2014-06-01 at the Wayback Machine - C implementation of Hazard Pointer and lock-free data structures; Atomic Ptr Plus - C/C++ library that has a Hazard Pointer implementation
A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
In a programming language, an evaluation strategy is a set of rules for evaluating expressions. [1] The term is often used to refer to the more specific notion of a parameter-passing strategy [2] that defines the kind of value that is passed to the function for each parameter (the binding strategy) [3] and whether to evaluate the parameters of a function call, and if so in what order (the ...
This is a list of the instructions in the instruction set of the Common Intermediate Language bytecode. Opcode abbreviated from operation code is the portion of a machine language instruction that specifies the operation to be performed. Base instructions form a Turing-complete instruction set.
