/**
* @brief eTaskConfirmSleepModeStatus - confirm no task is waiting for timeout.
*
* All the tasks except idle tasks are in suspended list. The system can stay in
* a low power state. This is a regression test for SMP to ensure uxNonApplicationTasks
* is set to configNUMBER_OF_CORES in the implementation.
*
* <b>Coverage</b>
* @code{c}
* #if ( INCLUDE_vTaskSuspend == 1 )
* else if( listCURRENT_LIST_LENGTH( &xSuspendedTaskList ) == ( uxCurrentNumberOfTasks - uxNonApplicationTasks ) )
* {
* ...
* eReturn = eNoTasksWaitingTimeout;
* }
* #endif
* @endcode
* ( listCURRENT_LIST_LENGTH( &xSuspendedTaskList ) == ( uxCurrentNumberOfTasks - uxNonApplicationTasks ) ) is true.
