Standard C Library Functions      pthread_barrierattr_destroy(3C)



NAME
     pthread_barrierattr_destroy, pthread_barrierattr_init - des-
     troy and initialize barrier attributes object

SYNOPSIS
     cc -mt [ flag... ] file... [ library... ]
     #include 

     int pthread_barrierattr_destroy(pthread_barrierattr_t *attr);


     int pthread_barrierattr_init(pthread_barrierattr_t *attr);


DESCRIPTION
     The pthread_barrierattr_destroy() function destroys  a  bar-
     rier  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  implementation  can  cause
     pthread_barrierattr_destroy()  to  set the object referenced
     by attr to an invalid value.


     The pthread_barrierattr_init() function initializes  a  bar-
     rier  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  initial-
     ize  one or more barriers, any function affecting the attri-
     butes 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 number is  returned
     to indicate the error.

ERRORS
     The pthread_barrierattr_init() function will fail if:

     ENOMEM    Insufficient memory exists to initialize the  bar-
               rier attributes object.
