The POSIX mutex concept is briefly explained to avoid deadlock in C programming. Therefore, we have employed the pthread_mutex_lock and pthread_mutex_unlock functions to perform that. Using these functions in our code snippets, we have ensured the usage of resources for one thread at a time....
Der Codeabschnitt, in dem mehrere Threads dasselbe Objekt im Speicher modifizieren, wird als kritischer Abschnitt bezeichnet. Im Allgemeinen sollte der kritische Abschnitt mit einer Art von Sperre geschützt werden, die andere Threads dazu zwingt, zu warten, bis der aktuelle Thread die Ausführung...
A mutex is similar to alock, but it can work across multiple processes; that is, it can be computer-wide as well as application-wide. TheMutexclass is located in theSystem.Threadingnamespace. The section of code that accesses the shared resource is called a critical or protected section. ...

Il controllo dei bug MUTEX_LEVEL_NUMBER_VIOLATION ha un valore pari a 0x0000000D.Questo controllo di bug viene visualizzato raramente.
We can lock and unlock the piece of code using Mutex in C++. We have to assign our code between these keywords. Below we can see the syntax for better understanding while using this in our program see below; std::mutexmtx; void function_name (arugeument_if _any) { ...
