Standard C Library Functions      pthreadbarrierattrdestroy(3C)



NAME
     pthreadbarrierattrdestroy, pthreadbarrierattrinit - des-
     troy and initialize barrier attributes object

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

     int pthreadbarrierattrdestroy(pthreadbarrierattrt *attr);


     int pthreadbarrierattrinit(pthreadbarrierattrt *attr);


DESCRIPTION
     The pthreadbarrierattrdestroy() function destroys  a  bar-
     rier  attributes  object. A destroyed attr attributes object
     can be reinitialized using  pthreadbarrierattrinit().  The
     results  of  otherwise  referencing  the object after it has
     been destroyed are undefined. An  implementation  can  cause
     pthreadbarrierattrdestroy()  to  set the object referenced
     by attr to an invalid value.


     The pthreadbarrierattrinit() 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  pthreadbarrierattrinit()   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
     pthreadbarrierattrdestroy() and pthreadbarrierattrinit()
     functions returns 0. Otherwise, an error number is  returned
     to indicate the error.

ERORS
     The pthreadbarrierattrinit() function will fail if:

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