pthread_mutex_t *mutex, const pthread_mutexattr_t *attr)
The pthread_mutex_init() function initializes a mutex object specified by the mutex parameter. The attr parameter can be used to specify additional attributes for the mutex object, such as whether it is a recursive mutex or a shared mutex.
The function returns zero on success and a non-zero error code on failure. Once a mutex object has been initialized, it can be used to synchronize access to shared resources between multiple threads.
Note: This function is part of the POSIX threads (pthread) library, which is a standard for thread programming in Unix-like operating systems.
