Synopsis. mutex_init (. mutex); Arguments. mutex. the mutex to be initialized. Description. Initialize the mutex to unlocked state. It is not allowed to initialize an already locked mutex.

Mutex is a synchronization primitive that grants exclusive access to the shared resource to only one thread. If a thread acquires a mutex, the second thread that wants to acquire that mutex is suspended until the first thread releases the mutex.

At the end of the main function when both the threads are done, the mutex is destroyed. The mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads. mutex offers exclusive, non-recursive ownership semantics: A calling thread owns a mutex from the time that it successfully calls either lock or try_lock until it calls unlock. /// A [`Mutex`] must first be initialised with a call to [`Mutex::init`] before it can be used. The /// [`mutex_init`] macro is provided to automatically assign a new lock class to a mutex instance. The pthread_mutex_init () function initializes the specified mutex.
