Имя (Name)
pthread_mutexattr_init, pthread_mutexattr_destroy - initialize
and destroy a mutex attributes object

Описание (Description)
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.
Возвращаемое значение (Return value)
On success, these functions return 0. On error, they return a
positive error number.
Стандарты (Conforming to)

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