220.127.116.11 Client Request Buffer
For the purposes of this example, it is assumed that a stream is open before this ROP is called. A complete ROP request buffer for the RopCommitStream ROP ([MS-OXCROPS] section 18.104.22.168) is a three-byte sequence formatted as follows.
0000: 5D 01 01
The three bytes refer to the RopId, LogonId, and InputHandleIndex fields described in [MS-OXCROPS] section 2.2.
RopId: 0x5D (RopCommitStream)
