* PARAMETERS

*
* 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.
