- 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
- 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
- How to implement an atomic counter - Stack Overflow
Fortunately, the value initializing constructor of an integral atomic is constexpr, so the above leads to constant initialization Otherwise you'd want to make it -say- a static member of a class that is wrapping this and put the initialization somewhere else
- 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
- Are primitive data types in c# atomic (thread safe)?
Yes an operation can be atomic or not, but there are specific data types that are referred to as being atomic types because they allow atomic operations due to their memory size requirements in regards to the word size on the system
- In C#, what does atomic mean? - Stack Overflow
I read this in the book C# 6 0 and the NET 4 6 framework: “assignments and simple arithmetic operations are not atomic” So, what does it exactly mean?
