[Solved] Identify the error in this shutdown sequence code snippet: void ShutdownTask(void *pvParameters) { vTaskDelete(NULL); // Cleanup code here } | FreeRTOS

FreeRTOS - Design Patterns for RTOS

Identify the error in this shutdown sequence code snippet:

void ShutdownTask(void *pvParameters) {
  vTaskDelete(NULL);
  // Cleanup code here
}

ATask should call vTaskStartScheduler() before deletion

BvTaskDelete(NULL) deletes all tasks, causing crash

CMissing call to vTaskSuspendAll() before deletion

DCleanup code runs after task deletion, so it never executes

Step-by-Step Solution

Solution:

Step 1: Understand vTaskDelete behavior
vTaskDelete(NULL) deletes the current task immediately, stopping execution at that point.
Step 2: Check code after deletion
Cleanup code after vTaskDelete(NULL) will never run because the task is deleted before it.
Final Answer:
Cleanup code runs after task deletion, so it never executes -> Option D
Quick Check:
vTaskDelete stops task immediately, no code after runs [OK]

Quick Trick: Code after vTaskDelete(NULL) won't run [OK]
