I asked this function based on this concept (maybe incorrect?!): Wherever a const can exist, a volatile can exist at the place.
The problem: we have critical path code that should never block. In many places it relies on configuration data, or similar, infrequently updated data from an external source.
I was looking for a thread-safe counter implementation using Interlocked that supported incrementing by arbitrary values, and found this sample straight from the Interlocked.CompareExchange documentat
In C++03 Standard observabl开发者_StackOverflow社区e behavior (1.9/6) includes reading and writing volatile data. Now I have this code:
The MSDN docs for \"volatile\" in Visual C++ indicate that writes have \"release semantics开发者_如何转开发\" and that reads have \"acquire semantics\", in addition to ensuring that reads always read
If I want to keep a global counter (e.g. to cou开发者_运维技巧nt number of incoming requests across multiple threads), then the best way to do in java would be to use a volatile int. Assuming, clojure
I have the following code that gets initialized as a static variable in a class: public class MyXlet extends Xlet {
(related to this question Is It Safe to Cast Away volatile?, but not quite the same, as that question relates to a specific instance)
I have a thread: class Foo extends Thread { boolean active = true; public void run() { while(active) { //do stuff
I dont understand those few statements that I read: because accessing a volatile variable never holds a lock, it is not
