init

此方法用于初始化 RiCOSTimer 对象。

特征符
RiCBoolean RiCOSTimer_init (RiCOSTimer *const me,
   timeUnit ptime, void (*cbkfunc)(void *), 
void *params);
参数
me

这是要初始化的 RiCOSTimer 对象

pTime

这是计时器的各个节拍之间的间隔时间。在大多数适配器中,时间单位都为毫秒;但是,这取决于特定的适配器实现。

cbkfunc

这是节拍计时器回调函数,用于通知计时器客户机已发出节拍。

params

这是回调函数的参数。

返回

如果成功,那么此方法返回 RiCTRUE

示例
RiCBoolean RiCOSTimer_init(RiCOSTimer * const me,
   timeUnit ptime, void (*cbkfunc)(void *), void *params)
{
   if (me == NULL) return RiCFALSE;
   me->cbkfunc = cbkfunc;
   me->param   = params;

   if (((RiCTimerManager*)params)->realTimeModel) {
      /****      VxWorks TickTimer(Real Time)      ****/
      me->m_Time  = ptime;
      /* Create a thread that runs the bridge, passing
         this as an argument. */
      me->ticks = cvrtTmInMStoTicks(me->m_Time);
      me->hThread = taskSpawn("timer", PRIORITY_HIGH, 0,
         SMALL_STACK, (int (*)())bridge, 
         (int)(void *)me /*p1*/, 0,0,0,0,0,0,0,0,0 );
      return me->hThread != ERROR;
   }
   else {
      /****      IdleTimer (Simulated Time)   ****/
      me->m_Time = 0; /* Just create context-switch
         until the system enters idle mode. */
      me->hThread = taskSpawn("timer", PRIORITY_LOW, 0,
         SMALL_STACK, (int (*)())bridge, (int)(void*)me,
         0,0,0,0,0,0,0,0,0);
      return RiCTRUE;
   }
}
