lpOutBuffer
A pointer to the output buffer that receives a USN followed by zero or more USN_RECORD_V2 or USN_RECORD_V3 structures.
The USN is a DWORDLONG value that represents the USN following the last record in the buffer. It can be used in a subsequent call to FSCTL_ENUM_USN_DATA to get the next set of records following those in the current output buffer.

...
  WORD          FileNameOffset;
  WCHAR         FileName[1];
} USN_RECORD_V3, *PUSN_RECORD_V3;

public struct OUTBUFF{
   public ulong usn; // 8 byte
   public USN_RECORD_V3 usnRecordV3; // 47 byte
   [MarshalAs(UnmanagedType.ByValArray, SizeConst = 508)]
   public byte[] fileName; // max 508
}

and then manually split the OUTBUFF.recordData at the offsets calculated
