- *  _CORE_mutex_Surrender
- *
- *  DESCRIPTION:
- *
- *  This routine frees a unit to the mutex.  If a task was blocked waiting for
- *  a unit from this mutex, then that task will be readied and the unit
- *  given to that task.  Otherwise, the unit will be returned to the mutex.
- *
- *  Input parameters:
- *    the_mutex            - the mutex to be flushed
- *    id                   - id of parent mutex
- *    api_mutex_mp_support - api dependent MP support actions
- *
- *  Output parameters:
- *    CORE_MUTEX_STATUS_SUCCESSFUL - if successful
- *    core error code              - if unsuccessful
