***奇怪的问题呀!***

我想在应用中传一个值给驱动，怎么值变了???

应用中:

ULONGLONG uFileSize = 3242344;
DeviceIoControl(
Device,
IOCTL_NETDISK_OPEN_FILE,
&uFileSize,
sizeof(ULONGLONG),
NULL,
0,
&bReturn,
NULL
);

驱动中:
case IOCTL_NETDISK_OPEN_FILE:
{
ULONGLONG uFileSize;
uFileSize = (ULONGLONG)pIrp->AssociatedIrp.SystemBuffer;

这时候uFileSize 怎么变成428870431了????
}
