  NAME

      pthread_attr_delete - Deletes a thread attributes object

  SYNOPSIS

      #include <pthread.h>

      int pthread_attr_delete(pthread_attr_t *attr);

  PARAMETERS

      attr                Thread attributes object deleted.

  DESCRIPTION

  The pthread_attr_delete() routine deletes a thread attributes object and
  gives permission to reclaim storage for the thread attributes object.
  Threads that were created using this thread attributes object are not
  affected by the deletion of the thread attributes object.

  The results of calling this routine are unpredictable if the value
  specified by the attr parameter refers to a thread attributes object
  that does not exist.

  RETURN VALUES

  If the function fails, errno may be set to one of the following values:

            Return   Error      Description
            ___________________________________________________________
               0                Successful completion.

              -1     [EINVAL]   The value specified by attr is invalid.
