Should we write our own? It is not complicated after all. I am thinking a
class like this would be good enough:
```c++
/**
* Lock guard for pthread_mutex_t object using RAII
* The Lock is automatically release when exiting current scope.
*/
class Lock {
public:
explicit Lock(pthread_mutex_t* mutex) : mutex_ptr_(mutex) {
pthread_mutex_lock(mutex_ptr_);
}
~Lock() { pthread_mutex_unlock(mutex_ptr_); }
private:
// no default constructor
Lock();
// prohibit copying
Lock(const Lock&);
Lock& operator=(const Lock&);
pthread_mutex_t* mutex_ptr_;
};
```
