188.8.131.52 Processing RopSetStreamSize
When the server receives a RopSetStreamSizeROP request buffer ([MS-OXCROPS] section 184.108.40.206) from the client, the server parses the buffer. The server responds with a RopSetStreamSizeROP response buffer. For details about how the server parses buffers and processes ROPs, see [MS-OXCROPS] section 220.127.116.11. For details about how the server formats buffers for the response, see [MS-OXCROPS] section 18.104.22.168.
The server sets the current size of the Stream object according to the value specified in the StreamSize field of the ROP request buffer. If the size of the stream is increased, the server MUST set the values in the extended stream to 0x00. If the size of the stream is decreased, the server discards the values that are beyond the end of the new size.
