UNSIGNED LONG 0x1000的输出格式

UNSIGNED LONG 0x1000的输出格式 [复制链接]

程序中有下面的代码:
ULONG                                length = 0;
LARGE_INTEGER                offset = { 0 };

...

if (IRP_MJ_WRITE == Irpsp->MajorFunction)
{
        //如果是写的irp请求，我们在irp stack中取得相应的参数作为offset和length
        offset = Irpsp->Parameters.Write.ByteOffset;
        length = Irpsp->Parameters.Write.Length;
        KdPrint(("IRP_MJ_WRITE:offset:%x.length:%ld!\n",offset.QuadPart,length));
}

WinDBG调试时显示的输出信息一直是下面这样,length是0
IRP_MJ_WRITE:offset:3e878800.length:0!

单步调试,在length = Irpsp->Parameters.Write.Length;这儿显示 length = UNSIGNED LONG 0x1000
但是下一步输出信息还是 IRP_MJ_WRITE:offset:3e878800.length:0!

不知道哪儿出问题了,是ULONG的输出格式不对么?要用什么?
谢了!

MARK，学习下！

KdPrint(("IRP_MJ_WRITE:offset:%lx.length:%ld!\n",offset.QuadPart,length));

好像.QuadPart是64-BIT,是不是该这样?
KdPrint(("IRP_MJ_WRITE:offset:%I64x.length:%ld!\n",offset.QuadPart,length));
