TI-RTOS例程问题

请问，这段TI-RTOS的例程代码是设置优先级的吧，函数里面的参数填什么呢，新手求问啊，谢谢啦

/* Construct writer/reader Task threads */
Task_Params_init(&taskParams);
taskParams.stackSize = TASKSTACKSIZE;
taskParams.stack = &task1Stack;
taskParams.priority = 1; 这个是配置优先级
Task_construct(&task1Struct, (Task_FuncPtr)task1Fxn, &taskParams, NULL);

taskParams.stack = &task2Stack;
taskParams.priority = 2;
Task_construct(&task2Struct, (Task_FuncPtr)task2Fxn, &taskParams, NULL);
