+# Mutex::TryLock
+
+```cpp
+bool TryLock()
+```
+
+尝试获取互斥锁（非阻塞）。如果锁可用则立即获取并返回 true，否则立即返回 false 而不阻塞。
+
+**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)
+
+**使用场景：** 适用于需要尝试获取锁但不希望阻塞的场景，如实现无锁算法或避免死锁。
+
+**示例：**
+
+```cpp
+Threading::Mutex mtx;
+volatile bool updated = false;
+
+void TryUpdate() {
+    if (mtx.TryLock()) {
+        updated = true;
+        mtx.Unlock();
+        printf("Update succeeded\n");
+    } else {
+        printf("Update skipped (lock held)\n");
+    }
+}
+```
