| * 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. |
