  pthread_mutexattr_destroy()

  NAME

    pthread_mutexattr_destroy(), pthread_mutexattr_init() - initialize or
    destroy a mutex attributes object

  SYNOPSIS

    #include 

    int pthread_mutexattr_destroy(pthread_mutexattr_t *attr);
    int pthread_mutexattr_init(pthread_mutexattr_t *attr);

  DESCRIPTION

    The pthread_mutexattr_init(2) function initializes the mutex attributes
    object referenced by the attr argument with default values. This object
    can be used in a call to pthread_mutex_init(2) to set the attributes of
    the mutex when it is initialized.

    The pthread_mutexattr_destroy(2) function destroys the mutex attributes
    object referenced by the attr argument.

  RETURN VALUES

    On success, both functions return 0; otherwise, an error code is returned.

  ERRORS

    The pthread_mutexattr_destroy() function can fail for the following
    reason:

    [EINVAL]
        The attr argument is invalid.

    The pthread_mutexattr_init() function can fail for the following reason:

    [ENOMEM]
        Not enough free memory exists to initialize the mutex attributes
        object.

    Neither function returns [EINTR].
