184.108.40.206 RopUnlockRegionStream ROP Request Buffer
RegionOffset (8 bytes): An unsigned 64-bit integer that specifies the number of bytes from the beginning of the stream where the beginning of the region to be unlocked is located.
RegionSize (8 bytes): An unsigned 64-bit integer that specifies the size, in bytes, of the region to be unlocked.
LockFlags (4 bytes): A set of bits that control the read/write access to the locked region. The value of the LockFlags field MUST be one of the values specified in section 220.127.116.11. In addition, it MUST be set to the same value that was used in the RopLockRegionStream ROP request buffer ([MS-OXCROPS] section 18.104.22.168) that was used to lock the region of bytes.
