wince中断流驱动的问题 [复制链接]

我参照教程上编写的流驱动，采用外部中断，显示挂载成功，但是XXX_int()好像没有执行，我在该函数入口处输出了打印信息，结果没有显示，另外我感觉
DWORD PBT_IntrThread(PVOID pArg)
{
      DWORD ret;

gPwrButtonIntrEvent = CreateEvent(NULL, FALSE, FALSE, NULL);



if (!(InterruptInitialize(g_PwrButtonSysIntr, gPwrButtonIntrEvent, 0, 0)))
{
RETAILMSG(1, (TEXT("ERROR: PwrButton: Interrupt initialize failed.\r\n")));
CloseHandle(gPwrButtonIntrEvent);
return 0;
}


while (1)
{
   ret = WaitForSingleObject(gPwrButtonIntrEvent, INFINITE);

   if((ret==WAIT_OBJECT_0)&&(g_bKillIST))
               {
                  if(PBT_IsPushed())
         {
      Sleep(20);
      if(PBT_IsPushed())
{
SetEvent(gReadKeyEvent[0]);

}
            }

                  }
                  else {

                  CloseHandle(gPwrButtonIntrEvent);
                  return 0;

                  }
                  InterruptDone(g_PwrButtonIrq);
      }

return 1;
}
函数执行是不是有问题呢？中断服务线程应该是一只执行啊，if((ret==WAIT_OBJECT_0)&&(g_bKillIST))此条件不满足以后线程不就退出了？？？中断触发或者线程关闭，大家看看是不是有问题？？
有一点我不明白的就是为什么我的XXX_INT也没有执行呢？挂载已经成功了,此函数不是在驱动加载的时候就执行的吗？？？请各位大侠解惑一下啊

把你的DEF文件，注册表中关于这个驱动的内容，以及XXX_Init都帖出来看一下。

如果XXX_Init都没执行，后边的中断当然都不行了

ustc2005

中断线程应该是在XXX_Init初始化的吧，如果XXX_Init没执行后边肯定都没用，所以先要让XXX_Init执行成功。

在应用程序里用createfile打开总是失败，DllEntry有信息输出注册表里也有，但是XXX_INIT里的打印信息却没有输出，入口第一条语句就是…………

fu2521

注册表中要有"Prefix"="XXX"的内容，def文件中要有XXX_Init导出声明，驱动源文件中要有XXX_Init函数，且这三个地方的XXX要保持一致，要三个字符。
