[wince5.0]关于interruptinitialize的使用问题，请教！
我目前是在一个wince5.0平台上写个小驱动，需要在init里启用一个中断，于是就想到了interruptinitialize()这个函数。现在的问题是如果在原BSP里的某个驱动里使用这个函数调用就没有问题，并且能完成任务；但是我自己写的驱动，编译完成后就总是出现调用错误，出错信息如下：
MyDriver - DLL_PROCESS_ATTACH
MyDriver - DEM_Init
+OALIntrEnableIrqs(1, 0x8c9902c8)
+BSPIntrEnableIrq(-1)
MyDriver - ~ DEM_Init

下面附上我在powerbutton驱动里init函数中的代码，在这里加载就可以。

// we are concerned that somebody might sysgen a version of the OS that doesn't
// contain the appropriate APIs.

当加上红色的代码时就会出错，当然，我已经将SYSINTR_TIMER2和IRQ_TIMER2在[BSP]\kernel\oal\intr.c文件中的BSPIntrInit里静态连接上了。
这个事情困扰了好几天，还是没找出问题所在。
[解决办法]
g_hHTimerEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
InterruptInitialize(SYSINTR_TIMER2, g_hHLTimerEvent, NULL, 0)
是不是多打了一個 L??

LZ，你的这个g_hHTimerEvent在哪儿使用的呢？该不会是在PwrButtonIntrThread线程里WaitForSingleObject的吧？
如果是的话那InterruptInitialize肯定会失败了~
在InterruptInitialize之前，不能使用即将关联的事件！
[解决办法]
把下面调个位置看看
//////////////////////////////////////....added by me.......................
if (!(InterruptInitialize(SYSINTR_TIMER2, g_hHLTimerEvent, NULL, 0)))
{
RETAILMSG(1, (TEXT("SYSINTR_TIMER2 INTR INIT Failed\r\n")));
}
////////////////////////////////////................end..................
if(g_hPwrBtnThread == NULL)
{
g_hPwrBtnThread = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE) PwrButtonIntrThread, NULL, 0, NULL);
if ( g_hPwrBtnThread == NULL)
{
DEBUGMSG(DBG_ATLAS_ZONE_INIT | DBG_ATLAS_ZONE_ERROR, (TEXT("Fatal Error! Failed to create PwrButton threads.\r\n")));
goto InitFailed;
}
}
