WebTest-and-Set Instruction. It is an instruction that returns the old value of a memory location and sets the memory location value to 1 as a single atomic operation. If one process is currently executing a test-and-set, no other process is allowed to begin another test-and-set until the first process test-and-set is finished. It is implemented as-. WebAtomic fetch-and-store. Reads the current value of this QAtomicPointer and then assigns it the newValue, returning the original value. This function uses release memory ordering semantics, which ensures that memory access before the atomic operation (in program order) may not be re-ordered after the atomic operation.
