Which of the following is the correct way to call vTaskGetRunTimeStats() to store the stats in a buffer named buffer?

AvTaskGetRunTimeStats(buffer);

BvTaskGetRunTimeStats(&buffer);

CvTaskGetRunTimeStats(buffer[]);

DvTaskGetRunTimeStats(*buffer);

Step-by-Step Solution

Solution:

Step 1: Check function parameter type
vTaskGetRunTimeStats() expects a pointer to a char array (string buffer), so passing the buffer name directly is correct.
Step 2: Analyze each option's syntax
vTaskGetRunTimeStats(buffer); passes the buffer correctly. vTaskGetRunTimeStats(&buffer); passes address of buffer pointer (wrong). vTaskGetRunTimeStats(buffer[]); uses invalid syntax. vTaskGetRunTimeStats(*buffer); dereferences buffer incorrectly.
Final Answer:
vTaskGetRunTimeStats(buffer); -> Option A
Quick Check:
Pass buffer name directly [OK]

Quick Trick: Pass buffer name directly, no & or * needed [OK]
