main函数代码如下：
```c
void fun(void * p)
{
	while(1)
	{
		
		rt_thread_delay（10）；
	}
}

static rt_uint32_t rt_thread6_stack[256];//线程栈
static rt_thread_t rt_thread6 = RT_NULL;

int main(void)
{
	rt_thread_init(rt_thread6, "111", fun, RT_NULL, &rt_thread6_stack, 							sizeof(rt_thread6_stack), 9, 100)；
	rt_thread_startup(rt_thread6);
	while(1)
	{
		rt_thread_delay(1000);
	}
}
```
