# SpinLock::try_lock
|
||||
|
||||
```cpp
|
||||
bool try_lock()
|
||||
```
|
||||
|
||||
STL 兼容的 `try_lock()` 方法,与 [`TryLock`](trylock.md) 等效。满足 STL `Lockable` 概念要求。
|
||||
|
||||
**参数:** 无
|
||||
|
||||
**返回:** `bool` - 获取成功返回 true,锁不可用返回 false
|
||||
|
||||
**复杂度:** O(1)
|
||||
|
||||
**线程安全:** ✅
|
||||
|
||||
**示例:**
|
||||
|
||||
```cpp
|
||||
Threading::SpinLock spinLock;
|
||||
|
||||
void STLCompatibleTry() {
|
||||
if (spinLock.try_lock()) {
|
||||
// 临界区操作
|
||||
spinLock.unlock();
|
||||
}
|
||||
}
|
||||
```
