我试图更好地理解驱动程序，并从头开始构建一个非常基本的驱动程序。
#include <ntddk.h>
VOID onUnload(IN PDRIVER_OBJECT pDriver_Object)
{
DbgPrint("Unloading Driver\n");
}
NTSTATUS DriverEntry(IN PDRIVER_OBJECT pDriver_Object, IN PUNICODE_STRING regPath)
{
DbgPrint("Driver Loaded");
(*pDriver_Object).DriverUnload = onUnload;
return(STATUS_SUCCESS);
}
我正在安装驱动程序签名的Windows 7 x64计算机上安装它。驱动程序安装得很好但是当我尝试启动它时，我得到：
[SC] StartService FAILED 6:
The handle is invalid.
在使用Windbg进一步调查后，我得到了一个：
*** Fatal System Error: 0x0000007e
(0xFFFFFFFFC0000005,0xFFFFF80002C7501D,0xFFFFF88002F89768,0xFFFFF88002F88FC0)
做！分析-v让我：
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff80002c7501d, The address that the exception occurred at
Arg3: fffff88002f89768, Exception Record Address
Arg4: fffff88002f88fc0, Context Record Address

似乎Windows甚至无法进入我的DriverEntry功能。有关如何解决此问题或进一步调试的任何想法？谢谢！
