FilterReplyMessage returned 0x801F0020

I couldn’t find any information about the return code. It is a very simple
user mode win32 console application. Here is the snippet of the source code:

FILTER_REPLY_HEADER ReplyHeader = {0};
ReplyHeader.MessageId = recvMsg.MessageHeader.MessageId;
hr = FilterReplyMessage( port,
&ReplyHeader,
sizeof( ReplyHeader ) );
if (!SUCCEEDED( hr ))
{
printf( “FilterReplyMessage returned error: 0x%X\n”, hr );
break;
}

Any information is appreciated.

It’s a standard system error code. Use FormatMessage() to decode it.
(Basically, the low 16 bits is the error code = 0020 = 32 =
ERROR_SHARING_VIOLATION).

Never mind. I found the definition in fltwinerror.h. It says:
“No waiter is present for the filter’s reply to this message”
