Deleting a task from another task

In order to delete a task from another task, blueTaskHandle needs to be passed to xTaskCreate and its value populated. blueTaskHandle can then be used by other tasks to delete BlueTask, as shown here:

TaskHandle_t blueTaskHandle;int main(void){    HWInit();    assert_param( xTaskCreate(BlueTask, "BlueTask", STACK_SIZE,                  NULL, tskIDLE_PRIORITY + 1, &blueTaskHandle) ==                   pdPASS);    xTaskCreateStatic( RedTask, "RedTask", STACK_SIZE, NULL,                       tskIDLE_PRIORITY + 1, RedTaskStack,                       &RedTaskTCB);    vTaskStartScheduler();    while(1);}void RedTask( void* argument ){    vTaskDelete(blueTaskHandle);}

The actual code in main.c results in the blue LED blinking for ~ 1 second before being deleted by RedTask. At this point, the blue LED stops ...
