 const struct sigevent *handler1(void *area, int id1)

   volatile double KernelStartExecutionTime;
   KernelStartExecutionTime = GetTimeStamp();   // calculating the time when the kernel //starts executing

 }


 /*kernel calls attach the interrupt function handler to the hardware interrupt specified by intr(i.e irq) */
// InterruptAttach() : Attach an interrupt handler to an interrupt source
// interrupt source is handler1 for this example

void ISR(void)
{
  /*  the software must tell the OS that it wishes to associate the ISR with a particular source of interrupts.
  /*  On x86 platforms, there are generally 16 hardware Interrupt Request lines (IRQs) */
  volatile int irq = 0;   //0 : A clock that runs at the resolution set by ClockPeriod()



  ThreadCtl (_NTO_TCTL_IO, NULL);
  id1 = InterruptAttach(irq, &handler1, NULL, 0, 0);    // handler1 is the ISR

}

场景：客户端-服务器通信-客户端是发送者，服务器是接收者。当服务器在以太网接口（UDP）上接收到数据时，服务器中的内核被触发。我在服务器端使用 QNX。服务器（即嵌入式 pc 目标）正在处理中断以触发嵌入式 pc 目标（包含 qnx）以获取注意力以执行新到达的数据。

我为内核创建了一个中断服务例程，但是如何检查上述代码是否正常工作。有人可以帮我吗？
