- c++ - How to use std::atomic efficiently - Stack Overflow
std::atomic is new feature introduced by c++11 but I can't find much tutorial on how to use it correctly So are the following practice common and efficient? One practice I used is we have a buff
- c++ - What exactly is std::atomic? - Stack Overflow
Objects of atomic types are the only C++ objects that are free from data races; that is, if one thread writes to an atomic object while another thread reads from it, the behavior is well-defined In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by std::memory_order
- . net - What operations are atomic in C#? - Stack Overflow
Is there a systematic way to know whether an operation in C# will be atomic or not? Or are there any general guidelines or rules of thumb?
- What is the difference between std::shared_ptr and std::atomic lt;std . . .
The atomic "thing" in shared_ptr is not the shared pointer itself, but the control block it points to meaning that as long as you don't mutate the shared_ptr across multiple threads, you are ok do note that copying a shared_ptr only mutates the control block, and not the shared_ptr itself
- What is the difference between atomic_int and int？
In addition to atomicity, atomic types also allow you to control the ordering of memory operations, which may be of vital importance For instance, even though writing to aligned int with mov instruction is atomic on x64, with atomic_int, compilers typically generate xchg thanks to the default sequential consistency ordering requirements
- Whats the difference between the atomic and nonatomic attributes?
The last two are identical; "atomic" is the default behavior (note that it is not actually a keyword; it is specified only by the absence of nonatomic -- atomic was added as a keyword in recent versions of llvm clang) Assuming that you are @synthesizing the method implementations, atomic vs non-atomic changes the generated code If you are writing your own setter getters, atomic nonatomic
- atomic operations and atomic transactions - Stack Overflow
Can someone explain to me, whats the difference between atomic operations and atomic transactions? Its seems to me that these two are the same thing Is that correct?
- 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?
