linux下该如何取消用setitimer设置的定时器呢？
void init_sigaction(void)
{
  struct sigaction tact;
  tact.sa_handler = drawFrame_proc;
  tact.sa_flags = 0;
  sigemptyset(&tact.sa_mask);
  sigaction(SIGALRM, &tact, NULL);
}

void init_time()
{
  struct itimerval value;
  value.it_value.tv_sec = 0;
  value.it_value.tv_usec = 40000;
  value.it_interval = value.it_value;
  setitimer(ITIMER_REAL, &value, NULL);
 }

请问该如何取消用setitimer设置的定时器呢。谢谢！

------解决方案--------------------
setitimer设置it_interval和it_value为零。
------解决方案--------------------
void uninit_time() 
{ 
struct itimerval value; 
value.it_value.tv_sec = 0; 
value.it_value.tv_usec = 0; 
value.it_interval = value.it_value; 
setitimer(ITIMER_REAL, &value, NULL); 
}
