NAME

       pthread_barrierattr_destroy, pthread_barrierattr_init - destroy and initialize barrier attributes object

SYNOPSIS

       cc -mt [ flag... ] file... [ library... ]
       #include <pthread.h>

       int pthread_barrierattr_destroy(pthread_barrierattr_t *attr);

       int pthread_barrierattr_init(pthread_barrierattr_t *attr);

DESCRIPTION

       The  pthread_barrierattr_destroy()  function  destroys a barrier attributes object. A destroyed attr attributes object can be reinitialized
       using pthread_barrierattr_init(). The results of otherwise referencing the object after it has been destroyed are undefined. An implementa-
       tion can cause pthread_barrierattr_destroy() to set the object referenced by attr to an invalid value.

       The  pthread_barrierattr_init()	function  initializes  a  barrier  attributes object attr with the default value for all of the attributes
       defined by the implementation.

       Results are undefined if pthread_barrierattr_init() is called specifying an already initialized attr attributes object.

       After a barrier attributes object has been used to initialize one or more barriers, any function affecting the attributes object (including
       destruction) does not affect any previously initialized barrier.

RETURN VALUES

       Upon  successful completion, the pthread_barrierattr_destroy() and pthread_barrierattr_init() functions returns 0. Otherwise, an error num-
       ber is returned to indicate the error.

ERRORS

       The pthread_barrierattr_init() function will fail if:

       ENOMEM	 Insufficient memory exists to initialize the barrier attributes object.

       The pthread_barrierattr_destroy() function may fail if:

       EINVAL	 The value specified by attr is invalid.

NAME

       pthread_barrierattr_destroy, pthread_barrierattr_init - destroy and initialize the barrier attributes object (ADVANCED REALTIME THREADS)

SYNOPSIS

       #include <pthread.h>

       int pthread_barrierattr_destroy(pthread_barrierattr_t *attr);
       int pthread_barrierattr_init(pthread_barrierattr_t *attr);

DESCRIPTION

       The  pthread_barrierattr_destroy() function shall destroy a barrier attributes object. A destroyed attr attributes object can be reinitial-
       ized using pthread_barrierattr_init(); the results of otherwise referencing the object after it has been destroyed are undefined. An imple-
       mentation may cause pthread_barrierattr_destroy() to set the object referenced by attr to an invalid value.

       The  pthread_barrierattr_init() function shall initialize a barrier attributes object attr with the default value for all of the attributes
       defined by the implementation.

       Results are undefined if pthread_barrierattr_init() is called specifying an already initialized attr attributes object.

       After a barrier attributes object has been used to initialize one or more barriers, any function affecting the attributes object (including
       destruction) shall not affect any previously initialized barrier.

RETURN VALUE

       If  successful,	the  pthread_barrierattr_destroy()  and pthread_barrierattr_init() functions shall return zero; otherwise, an error number
       shall be returned to indicate the error.

ERRORS

       The pthread_barrierattr_destroy() function may fail if:

       EINVAL The value specified by attr is invalid.

       The pthread_barrierattr_init() function shall fail if:

       ENOMEM Insufficient memory exists to initialize the barrier attributes object.

       These functions shall not return an error code of [EINTR].

EXAMPLES

       None.

APPLICATION USAGE

       The pthread_barrierattr_destroy() and pthread_barrierattr_init() functions are part of the Barriers option and need not be provided on  all
       implementations.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
