rtlcopymemory导致蓝屏

[qq_35889047]

在minifilter通信函数里想把传过来的字符串分成两截处理，但是因为字符串本身比较大，尾部那截进行内存拷贝时一直会因为分页问题出现page_fault_in_nonpaged_area的错误，请问怎么修改好一点

NTSTATUS
MiniMessage(
	__in PVOID ConnectionCookie,
	__in_bcount_opt(InputBufferSize) PVOID InputBuffer,
	__in ULONG InputBufferSize,
	__out_bcount_part_opt(OutputBufferSize, *ReturnOutputBufferLength) PVOID OutputBuffer,
	__in ULONG OutputBufferSize,
	__out PULONG ReturnOutputBufferLength
)
{
	

	PAGED_CODE();

	UNREFERENCED_PARAMETER(ConnectionCookie);
	UNREFERENCED_PARAMETER(OutputBufferSize);
	UNREFERENCED_PARAMETER(OutputBuffer);
	if ((InputBuffer != NULL) &&
		(InputBufferSize >= sizeof(char)))
	{
		UNICODE_STRING receive;
		UNICODE_STRING fuck;
		KStr_Init(&head,MAX_PATH);
		KStr_Init(&tail, MAX_PATH);
		CHAR_TO_UNICODE_STRING((char *)InputBuffer,&receive);
		RtlCopyMemory(head.Buffer,receive.Buffer,2*sizeof(WCHAR));
		head.Length =2*sizeof(WCHAR);
		RtlCopyMemory(tail.Buffer, receive.Buffer+2*sizeof(WCHAR),receive.Length-2*sizeof(WCHAR));
		tail.Length = receive.Length - 2* sizeof(WCHAR);
	}
	return STATUS_SUCCESS;
}

我睿智了，改好了，自己tail截取的起始地点不对真实睿智
