函数原型：int tick_switch_to_oneshot(void (*handler)(struct clock_event_device *))

返回类型：int

参数：

类型参数名称
void (*handler
75  td等于this_cpu_ptr( & Tick devices)
76  dev等于evtdev
78  如果非dev或非features按位与CLOCK_EVT_FEAT_ONESHOT的值或非tick_device_is_functional(dev)则
81  打印信息("Clockevents: could not switch to one-shot mode:")
82  如果非dev则
83  打印标准信息(" no tick device\n")
84  否则
85  如果非tick_device_is_functional(dev)则打印标准信息(" %s is not functional.\n", name)
87  否则打印标准信息(" %s does not support one-shot mode.\n", name)
91  返回:负EINVAL
94  mode等于TICKDEV_MODE_ONESHOT
95  event_handler等于handler
