- Is there a difference between the _Atomic type qualifier and type . . .
Atomic type specifiers :-:) Syntax: _Atomic ( type-name ); You can declare an atomic integer like this: _Atomic(int) counter; The _Atomic keyword can be used in the form _Atomic(T), where T is a type, as a type specifier equivalent to _Atomic T Thus, _Atomic(T) x, y; declares x and y with the same type, even if T is a pointer type This allows for trivial C++0x compatibility with a C++ only
- What does atomic mean in programming? - Stack Overflow
In the Effective Java book, it states: The language specification guarantees that reading or writing a variable is atomic unless the variable is of type long or double [JLS, 17 4 7] What do
- c++ - Are +=, |=, = etc atomic? - Stack Overflow
2 ++ might be atomic on your compiler platform, but in the c++ specs it is not defined to be atomic If you want to make sure to modify a value in an atomic way, you should use the appropiate methods, like Interlocked* on windows Same for all the other routines If you want atomic operations, you should use the appropiate calls, not the
- What are atomic operations for newbies? - Stack Overflow
Everything works Note that "atomic" is contextual: in this case, the upsert operation only needs to be atomic with respect to operations on the answers table in the database; the computer can be free to do other things as long as they don't affect (or are affected by) the result of what upsert is trying to do

- When do I really need to use atomic lt;bool gt; instead of bool?
You need atomic<bool> to avoid race-conditions A race-condition occurs if two threads access the same memory location, and at least one of them is a write operation If your program contains race-conditions, the behavior is undefined
- atomic - Java - using AtomicInteger vs Static int - Stack Overflow
- AtomicInteger is used to perform the atomic operation over an integer, its an alternative when you don't want to use synchronized keyword - Using a volatile on a Non-Atomic field will give inconsistent result int volatile count; public void inc(){ count++ } - static will make a variable shared by all the instances of that class, But still it will produce an inconsistent result in multi
