Locking multiple mutexes

Question

I\'m wondering if it\'s possible to lock multiple mutexes at the same time, like:

 Mutex1.Lock();
 {
     Mutex2.Lock();
     {
          // Code locked by m         


        

Answer 1

std::lock seems to exist for this purpose.

Locks the given Lockable objects lock1, lock2, ..., lockn using a deadlock avoidance algorithm to avoid deadlock. The objects are locked by an unspecified series of calls to lock, try_lock, unlock. If a call to lock or unlock results in an exception, unlock is called for any locked objects before rethrowing.
