C++核心准则CP.44:记得为lock_guards和unique_locks命名

CP.44: Remember to name your lock_guards and unique_locks

CP.44:记得为lock_guards和unique_locks命名

Reason（原因）

An unnamed local objects is a temporary that immediately goes out of scope.

无名局部变量是马上离开作用域的临时变量。

Example（示例）

unique_lock<mutex>(m1);
lock_guard<mutex> {m2};
lock(m1, m2);

This looks innocent enough, but it isn't.

这些代码看起来没有任何问题，但是事实并非如此。

Enforcement（实施建议）

Flag all unnamed lock_guards and unique_locks.

标记所有未命名的lock_guard和unique_locks。
