➲ vTaskSuspendAll - Suspends all real time kernel activity while keeping interrupts (including the kernel tick) enabled ➲ xTaskResumeAll - Resumes real time kernel activity following a call to vTaskSuspendAll (). After a call to xTaskResumeAll () the kernel will take control of which task is executing at any time
Task Utilities ➲ xTaskGetTickCount - count of ticks since vTaskStartScheduler was called ➲ xTaskGetNumberOfTasks - number of tasks that the real time kernel is currently managing ➲ vTaskList - Lists all the current tasks
