minifilter全局变量问题

[qq_35889047]

各位大佬，我最近在用minifilter做一个目录保护，现在从外面导入了字符串数组

char* manu[MAX_PATH_NUM];
int path_num_count = 0;
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
)
{
	NTSTATUS status;

	PAGED_CODE();

	UNREFERENCED_PARAMETER(ConnectionCookie);
	UNREFERENCED_PARAMETER(OutputBufferSize);
	UNREFERENCED_PARAMETER(OutputBuffer);
	if ((InputBuffer != NULL) &&
		(InputBufferSize >= sizeof(char)))
	{
		
		manu[path_num_count] = (char *)InputBuffer;
		DbgPrint("inputbuffer:%s\r%s\n",(char *)InputBuffer,manu[path_num_count]);
		path_num_count++;
	}
		return STATUS_SUCCESS;
}

后续的处理函数进行字符串比对的时候经常发现manu数组里面值为空，这个问题怎么解决啊？
