| kBool kAtomic32s_CompareExchange | ( | kAtomic32s * | atomic, |
| k32s | oldValue, | ||
| k32s | value | ||
| ) |
Conditionally exchanges the value of an atomic variable.
If the atomic value is equal to the oldValue argument, then it is replaced by the value argument.
This method is thread-safe. Implements a full memory barrier.
| atomic | Pointer to atomic variable. |
| oldValue | Previous atomic value. |
| value | New atomic value. |
