Solution:Step 1: Understand heap memory impact on task creationIf the system heap is exhausted, xTaskCreate() cannot allocate stack and control structures, so it fails.Step 2: Check return value on failureOn failure, xTaskCreate() returns pdFAIL, so "Fail" is printed.Final Answer:Fail -> Option CQui

[Solved] Given the code:BaseType_t res = xTaskCreate( vTask, "T2", 500, NULL, 5, NULL); if(res == pdPASS) printf("Success\n"); else printf("Fail\n");What will be printed if the system runs out of heap memory? | FreeRTOS

FreeRTOS - Task Creation and Management

Given the code:

BaseType_t res = xTaskCreate(
  vTask, "T2", 500, NULL, 5, NULL);
if(res == pdPASS) printf("Success\n"); else printf("Fail\n");

What will be printed if the system runs out of heap memory?

ACompilation error

BSuccess

CFail

DNo output

Step-by-Step Solution

Solution:

Step 1: Understand heap memory impact on task creation
If the system heap is exhausted, xTaskCreate() cannot allocate stack and control structures, so it fails.
Step 2: Check return value on failure
On failure, xTaskCreate() returns pdFAIL, so "Fail" is printed.
Final Answer:
Fail -> Option C
Quick Check:
Heap exhaustion causes pdFAIL = "Fail" [OK]

Quick Trick: No heap memory means xTaskCreate returns pdFAIL [OK]

Common Mistakes:

Assuming NULL task handle causes failure
Thinking success prints even on failure
Ignoring heap memory limits
