Identify the error in this code snippet intended to get the stack high water mark of a task named myTaskHandle:

UBaseType_t mark = uxTaskGetStackHighWaterMark(myTaskHandle);

Assume myTaskHandle is a valid task handle.

AReturn type should be int, not UBaseType_t

BFunction name is incorrect, should be uxGetStackHighWaterMark

CParameter should be NULL to get any task's high water mark

DNo error, code is correct

Step-by-Step Solution

Solution:

Step 1: Verify function and parameter usage
uxTaskGetStackHighWaterMark takes a task handle to get that task's high water mark. Using myTaskHandle is valid.
Step 2: Check return type and function name
Return type UBaseType_t is correct. Function name is correct as per FreeRTOS API.
Final Answer:
No error, code is correct -> Option D
Quick Check:
Correct function and parameter usage means no error [OK]

Quick Trick: Use task handle parameter for specific task, NULL for current task [OK]
