# SpinLock::Lock
```cpp
void Lock()
```
获取自旋锁。如果锁已被其他线程持有则使用忙等待spin持续轮询直到获取到锁。
**参数:**
**返回:**
**复杂度:** 平均 O(1),最坏情况取决于竞争程度
**注意:**
- 适用于临界区极短(几个 CPU 指令)的场景,避免线程切换开销。
- 在锁持有时间较长或多核竞争激烈时,会浪费大量 CPU 周期,此时应使用 Mutex。
- 同一线程不可重复 Lock 同一个 SpinLock。
**示例:**
```cpp
Threading::SpinLock spinLock;
int64_t fastCounter = 0;
void IncrementFast() {
spinLock.Lock();
++fastCounter;
spinLock.Unlock();
}
```
