The following C code examples illustrate two threads that share a global integer i. The first thread uses busy-waiting to check for a change in the value of i : #include <pthread.h> #include <stdatomic.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> /* i is global, so it is visible to all functions.
The following example of the policy file from "The Design and Implementation of Tripwire: A File System Integrity Checker" by Spafford and Kim makes use of the preprocessing language. Here it is used to ignore the directory with printer logs on a specific host, and this directory will be scanned on all other hosts.
[3]: 288 For example, iteration over a directory structure could be implemented by a function class instead of more conventional loop pattern. This would allow deriving various useful information from directories content by implementing a visitor functionality for every item while reusing the iteration code. It's widely employed in Smalltalk ...
Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff. The transformation can be undertaken manually by the programmer or by an optimizing compiler.
Oct. 2—The fate of a Derry Township man hinges on whom jurors believe. Prosecutors plan to present evidence during trial this week that William Joseph Dankesreiter Jr., 63, set up a trip wire at ...
The key insight in the algorithm is as follows. If there is a cycle, then, for any integers i ≥ μ and k ≥ 0, x i = x i + kλ, where λ is the length of the loop to be found, μ is the index of the first element of the cycle, and k is a whole integer representing the number of loops.
Oct. 6—A Derry Township man accused of installing a trip wire to cause the fatal fall of his wife three years ago was found not guilty Friday of attempted murder. Westmoreland County prosecutors ...
A tripwire is a passive triggering mechanism. Typically, a wire or cord is attached to a device for detecting or reacting to physical movement. Military applications
