      * ------------------------------------------------------
      * DOCPUBLIC
      *      Initializes a condition variable attributes object
      *      with default attributes.
      *
      * PARAMETERS
      *      attr
      *              pointer to an instance of pthread_condattr_t
      *
      *
      * DESCRIPTION
      *      Initializes a condition variable attributes object
      *      with default attributes.
      *
      *      NOTES:
      *              1)      Use to define condition variable types
      *              2)      It is up to the application to ensure
      *                      that it doesn't re-init an attribute
      *                      without destroying it first. Otherwise
      *                      a memory leak is created.
      *
      * RESULTS
      *              0               successfully initialized attr,
      *              ENOMEM          insufficient memory for attr.
