Creating and Destroing Mutexes

#include <pthread.h>
void pthread_mutex_init(pthread_mutex_t *mutex, const pthread_mutexattr_t *attr);
void pthread_mutex_destroy(pthread_mutex_t *mutex);
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

Mutex variables must be declared with type pthread_mutex_t and initialized before they can be used. There are two ways to initialize a mutex variable:

• Statically, at declaration time using PTHREAD_MUTEX_INITIALIZER.

• Dynamically, using pthread_mutex_init(). This allows setting attributes for the mutex object.
