Reparse Filter response to FSCTL_SET_REPARSE_POINT

Is there any special processing I should be doing on this IOCTL - I have
written a filter driver, but am unable to create the reparse point. Do I
have to do anything special at installation - I don’t have an “OFFICIAL”
microsoft reparse tag yet, but we’re not at that point. Every attempt I
have made to set the reparse point has been met with error code 4392 (“The
data present in the reparse point buffer is invalid.”).

Belay that - IP error (Idiot Programmer) - I sorted out my problem right
after I posted the message. I wasn’t creating the file as a reparse point
since I commented out the FILE_ATTRIBUTE_REPARSE_POINT flag. I hope I
haven’t wasted your time.
