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.

int pthread_mutex_init(pthread_mutex_t *mutex, const pthread_mutexattr_t A thread attempting to lock a mutex that is already locked by another thread is
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.
