[Solved] Identify the error in this FreeRTOS memory management code: void *ptr = pvPortMalloc(50); // Missing NULL check memcpy(ptr, source, 50); | FreeRTOS

FreeRTOS - Memory Management

Identify the error in this FreeRTOS memory management code:

void *ptr = pvPortMalloc(50);
// Missing NULL check
memcpy(ptr, source, 50);

ANot checking if pvPortMalloc returned NULL before use

BUsing memcpy instead of memmove

CAllocating too much memory

DForgetting to free ptr immediately

Step-by-Step Solution

Solution:

Step 1: Review memory allocation safety
pvPortMalloc can return NULL if allocation fails; using ptr without check risks crash.
Step 2: Identify missing safety check
The code uses ptr directly without verifying it is not NULL.
Final Answer:
Not checking if pvPortMalloc returned NULL before use -> Option A
Quick Check:
Always check allocation result before use [OK]

Quick Trick: Check pvPortMalloc result before using pointer [OK]
