FreeRTOS - Task Notifications

Which of the following is the correct syntax to send a notification using xTaskNotifyGive() to a task handle named xTaskHandle?

AxTaskNotifyGive(xTaskHandle, 1);

BxTaskNotifyGive(&xTaskHandle);

CxTaskNotifyGive(xTaskHandle);

DxTaskNotifyGive();

Step-by-Step Solution

Solution:

Step 1: Recall function signature
xTaskNotifyGive() takes a task handle as a parameter, not a pointer or extra arguments.
Step 2: Check each option
xTaskNotifyGive(xTaskHandle); correctly passes the task handle. xTaskNotifyGive(&xTaskHandle); passes address (wrong), C adds an extra argument (wrong), D has no argument (wrong).
Final Answer:
xTaskNotifyGive(xTaskHandle); -> Option C
Quick Check:
Correct syntax = xTaskNotifyGive(xTaskHandle); [OK]

Quick Trick: Pass the task handle directly without extra arguments [OK]
