pthread_mutexattr_init, pthread_mutexattr_destroy - initialize and destroy a mutex attributes object

       The  pthread_mutexattr_init()  function  initializes  the mutex attributes object pointed to by attr with
       default values for all attributes defined by the implementation.

       The results of initializing an already initialized mutex attributes object are undefined.

       The pthread_mutexattr_destroy() function destroys a mutex attribute  object  (making  it  uninitialized).
       Once a mutex attributes object has been destroyed, it can be reinitialized with pthread_mutexattr_init().

       The results of destroying an uninitialized mutex attributes object are undefined.

       Subsequent  changes  to  a mutex attributes object do not affect mutex that have already been initialized
       using that object.

       On success, these functions return 0.  On error, they return a positive error number.
