Mutex and Semaphore in Java both used to provide mutual exclusion for critical section of code but they are completely different to each other. If you want a block of code can be only executed by one thread at a given time you usually lock that portion of code using a mutext which is ...
Let’s say now Shopper has 3 identical Laptops and 3 identical keys. Semaphore is the number offree identical Laptop keys. The semaphore count – the count of keys – is set to 3 at beginning (all three Laptops are free), then the count value is decremented as Customer are coming in...

The named mutex isshared between the threads of different process.In Linux, the mutexes are shared only between the threads of the sameprocess. To achieve the same functionality in Linux,a System V semaphorecan be used (seeResourcesfor a link to Part 2 of this series).In Windows, wait ...

As the documentation forCreateEventclearly spells out, if the named synchronization object already existed, CreateEvent API (and CreateMutex and CreateSemaphore) opens the object for EVENT_ALL_ACCESS (or SEMAPHORE_ALL_ACCESS or MUTEX_ALL...
