FreeRTOS - Task Priorities

Which of the following is the correct syntax to change a task's priority using vTaskPrioritySet()?

TaskHandle_t xTaskHandle;
// Change priority to 3
_____;

AvTaskPrioritySetPriority(xTaskHandle, 3);

BvTaskPrioritySet(xTaskHandle, 3);

CvTaskPrioritySet(3, xTaskHandle);

DvTaskSetPriority(xTaskHandle, 3);

Step-by-Step Solution

Solution:

Step 1: Recall the function signature
The correct function is vTaskPrioritySet(TaskHandle_t xTask, UBaseType_t uxNewPriority), so the task handle comes first, then the new priority.
Step 2: Check the options
vTaskPrioritySet(xTaskHandle, 3); matches the correct syntax exactly. Options A, B, and D either swap parameters or use incorrect function names.
Final Answer:
vTaskPrioritySet(xTaskHandle, 3); -> Option B
Quick Check:
Correct syntax = vTaskPrioritySet(task, priority) [OK]

Quick Trick: Function name and parameter order matter: task handle first [OK]
