[问题] WdfRequestMarkCancelable会BSOD?

楼主: bluestar8783 (蓝星)   2013-07-10 11:48:39
上层App对底层要资料,但当Driver程式中若是执行到
WdfRequestMarkCancelableEx的话会跑出BSOD (需长时间Run App)
其错误讯息会跑出
我有查看其传入的两个参数,都不是NULL
FAULTING_SOURCE_CODE:
744: PFN_WDF_REQUEST_CANCEL EvtRequestCancel
745: )
746: {
747: return ((PFN_WDFREQUESTMARKCANCELABLEEX) WdfFunctions[
WdfRequestMarkCancelableExTableIndex])(WdfDriverGlobals,
Request, EvtRequestCancel);
> 748: }
749:
750: //
751: // WDF Function: WdfRequestUnmarkCancelable
不知道问题大概是出在哪里呢?
有什么提示能够提供呢?
感激!
