I am looking for a way to guarantee that any time a thread locks a specific resource, it is forced to release that resource after a specific period of time (if it has not already released it). Envision a connection where you need to limit the amount of time any...
Does is make sense to do something like putting a std::lock_guard in an extra scope so that the locking period is as short as possible?
Do threads blocked by a std::mutex::lock() or a condition variable sleep in a way that frees the core for other processes, or am I required to manually put these threads to sleep? And if true, would std::mutex::try_lock() allow for a way to spin the thread without sleeping?
Is a mutex defined statically in a function body able to lock properly? I am currently using this pattern in my logger system, but I have not tested it's thread safety yet.
I am using C++11 and I have a std::thread which is a class member, and it sends information to listeners every 2 minutes. Other that that it just sleeps. So, I have made it sleep for 2 minutes, then send the required info, and then sleep for 2 minutes again.

I have a multi threaded C++ program which simulates a car workshop. Basically a car is a thread here and a station is a resource. It works like this: Car enters a workshop and it has a list of stations (just ints), that it has to visit, to get repaired....
Using cout in multiple threads might result in interleaved output. So I tried to protect cout with a mutex.
Moving forward with Concurrency In Action I have reached the following example. Tha author states that if we everytime lock 2 mutexes in the same order, then we are guaranteed to avoid deadlocks. Consider this example from the book:
Here we are:Do we really need to lock mutex in the get function? We are only providing read only access. What if we do not?
