FreeRTOS - Task Creation and Management

Why does xTaskCreate() require a pointer to a TaskHandle_t variable instead of returning the handle directly?

ABecause returning handles directly is not supported in C

BTo prevent tasks from accessing their own handles

CTo save memory by not copying the handle

DTo allow the function to return a status and provide the handle via pointer

Step-by-Step Solution

Solution:

Step 1: Understand function return and output parameters
xTaskCreate() returns a status code indicating success or failure.
Step 2: Reason why handle is passed by pointer
Since the return value is used for status, the task handle is returned via a pointer parameter to provide both pieces of information.
Final Answer:
To allow the function to return a status and provide the handle via pointer -> Option D
Quick Check:
Status via return, handle via pointer parameter [OK]

Quick Trick: Return status, pass handle pointer to get task handle [OK]
